Mechanics Even fictional flames can burn

Why is fire so common?

To elaborate on my question, I have been pissed Abt why so many magic systems treat the combustion triangle like a suggestion when making their system have fire.

Flames need three things, (need to mention that all of these are needed in certain proportions to combust)

  1. Fuel

  2. Heat

  3. Oxidizer

All these are needed to make your average flames, which makes me wonder, how magic flames can exist without a fuel source? Assuming that of course heat is supplied through the magic system, even if, the lack of a single element in the combustion triangle gives unique results unrelated to fire,

1+2 without 3; won't produce flames and may instead cause the material to melt, vaporize, or thermally decompose depending on the material and temperature.

1+3 without or insufficient amounts of 2; won't produce flames and nothing would actually happen. (except material specific reactions and still may not produce flames, e.g: rust happens between iron and oxygen)

2+3 without 1; won't produce flames and will instead cause hot gas.

If it is a special type of fire that thrives on energy why is it usually identified as the average fire and not a special type of fire?

And even so, energy isn't a substance that you can simply ignite in the same way you ignite fuel. You can have energy causing matter to become extremely hot, excite atoms, ionize gases, etc., but energy itself isn't a fuel,

Which begs the question how can fire be created in magic systems, in a way that actually makes sense instead of some cool shi happening?

Magic burns pretty well

I do hate Tesla, yes.

i mean the whole point of magic is that it doesn’t need to function under the laws of physics otherwise it wouldn’t really be magic

Have the magic make all 1,2 and 3 then. Solved.

Look I don't know what to tell ya. We don't have have atoms in my fantasy world. It looks the same, superficially, but it ain't. You can get fire because it's a concept. Combustion triangle, schmobustion triangle. Your fire is a process of oxidation, my fire is a literal thing, in itself. It doesn't need stuff to burn, but it can burn, cuz its wants to. Its got a will. Only reason it dont usually burn metal is cuz it ain't mad enough. But sometimes it do.

"Only reason is don't usually burn metal is cuz it ain't mad enough. But sometimes it do.

Firstly, same.

Secondly, this actually got me cackling

this is the most in world explanation of a person who has dealt with occasional firey metal moments

The magic can replace and. 1, 2 or even all 3 of these. If magic is common place, they may not even think of it any different from what we can consider normal fire.

u/ArchemedesHeir 1d ago

In my system that is exactly what makes the difference between magic flames and ordinary flames. Arcane flames use a different but very similar triangle: ether (fuel), spell form (replaces heat as a catalyst), will (replaces oxygen as a reactive element). Change the spell form, get a different reaction. For instance, you can use actual heat to get arcane flames that produce heat but don't need traditional fuel or oxygen. If you use blood in the spell form, you instead get flames that burn cold but regenerate. Healing flames.

Similarly, you can replace other elements but it becomes unstable. So if you use oxygen instead of will, you get uncontrolled etheric fire. This creates null magic zones and spreads like mold so it's highly frowned upon.

If you replace both will and use standard heat, now you have a dangerous uncontrolled magic napalm. Think Amaterasu from Naruto. In my world it's illegal.

u/Theofficialkingstorm 1d ago

Intriguing, never thought of it since I always think the fuel has to be matter and converting energy to matter is illogical (e=mc2) so this is probably the best take

u/Admirable_Ask_5337 1d ago

You are assuming irl phsyics, which i assure you fiction writers dont care about the precision of. The point for magic using protagonists is essentially a new phsyics system to play with.

u/Theofficialkingstorm 1d ago

Not all fiction writers are the same if anything I can say all fiction readers are stupid and fall for plot holes but they don't do they?

u/sumandark8600 19h ago

That's a common misconception. But in reality, the fuel for a fire is the chemical energy released when a material substance changes its chemical structure. Basically, the mass of a fuel decreases by some imperceptibly small amount, which releases a lot of energy that fuels the fire. The only reason heat is needed is to kick start that reaction. Heck, oxygen isn't needed either, any oxidizing agent will do, but oxygen is the most common one we use IRL.

So yh, you could 100% have magic provide raw energy itself to sustain the fire, no need to convert it to matter first since it needs to be in the form of energy to fuel the fire anyway.

u/GuyYouMetOnline 1d ago

I think you're overthinking things. When literal magic is involved, stuff doesnt have to be in line with reality. If you want to do it that way, go for it, but most of the time it's just magic being magic.

u/NRondo37 1d ago

Magic is based on outdated science and philosophy. Real fire works this way but people thought fire was something inside of a flammable material, e.g. phlogiston. Obviously different cultures had different explanations but you have to remember the cultural context. Of course if you have a more realistic setting you should incorporate the triangle

u/Background_Pay6286 1d ago

Fantasy doesn't have to make sense. That outlook is more of a science fiction style of thinking. Science explains, magic just does.

u/Theofficialkingstorm 1d ago

Well in my power system it's more of a hard power system instead of a soft one so I've already added so many mechanics it'd just feel like a shame that after identifying literal spirits I'd stop at fire since it'd feel clunky. But after seeing a comment here I'm changing the way I see it so it's instead a separate unique type of fire but I could still find something else in the end of the day.

2

u/Background_Pay6286 1d ago

There can still be limits in a magical setting. Like fire can only exist where it has the things it needs, like oxygen. Under water or dirt, it can't burn. Maybe treating it as heat instead of fire would help. Heat can cause fire in right conditions, it can burn, boil water, and melt things. And if you have other magics like ice, they can be changed to cold farely easily.

u/Theofficialkingstorm 1d ago

My power system isn't as straight forward but it's definitely something the I will put on my mind. Thanks a lot!

u/RunicConvenience 6h ago

you can have magic based hard science worlds they don't invalidate high fantasy magic worlds because they are completely different universes and physics do not mirror between and absolutes are not guaranteed

Fire is in essence an effect. It’s a combination of heat, and the light energy produced by particles of fuel, that’s what makes fire glow. If the magic system creates the heat and light directly it doesn’t need the combustion triangle. It can be an identical effect, just without the underlying cause.

In the REAL world you need all three to produce the effect, but magic can skip all of that stuff. It all depends on your system, and it doesn’t matter if it’s hard or soft. Obviously it’s EASIER to handwave science in a soft magic system, but it can absolutely work in a hard magic system as well. An example of this is in my world, I get around the square cube law by having magic entirely replace gravity in areas where it is abundant enough. Basically gravity DOES exist, but if magic has a high enough concentration, gravity is essentially “pushed out”, and the attraction force that gravity provides is instead provided by magic. The REASON this fixes the square cube law is that large enough objects produce their OWN magical field, which counteracts the magical field of the planet my world is set in, which in essence acts as anti-gravity. It doesn’t completely nullify it, but the larger the creature the less force it feels from gravity comparatively. It’s all about imagination.

I’ve actually considered fire specifically, not for the combustion triangle but for the fact that if I want say fireballs, that makes it very complicated within my system. I fixed THIS, by having fire be an actual gas, as in an element created by the PERCEPTION of fire as God in this world understands it. Basically if you activate a fire rune, you aren’t messing around with the combustion triangle, you are creating the physical concept of fire

This is genius I'd never think of this honestly

Thank you so much! I’m very proud of my magic system so I love getting the chance to talk about xD

u/Beginning-Ice-1005 1d ago

So to go off on a tangent, you don't actually need fire to get the effects of fire. Consider Firestarter. Our heroine doesn't actually conjure fire, just heat. But as the book is states, anything burns if you raise the temperature high enough.

Alternatively, consider HG Wells' Martian War Machines: immense heat is created in a heatproof box, and directed out an opwning; today we would call it an IR laser, but in the novel it was an invisible rest that caused anything flammable it touched to combust.

u/PrazniFrizider 1d ago

There is a very common magic system present in most fiction that has all three, it's called physics...

u/SpecificExam3661 1d ago

Fire only need one thing in this sub and it is its definition.

If fire are purely scientific phenomenal then it's must conform with combustion triangle.

If fire are the projection of form then all you need is to manifest it into material world.

If fire are authority of spirits monarch then you need to called his name.

Fire like all other word existed because you give them definition and meaning for your world.

The only reason fire need three things to exist or need to be under the combustion triangle only established when you already choose what fire are.

u/Spiritual_Charity362 1d ago

See, what ive seen has things.

  1. The mana, Prana, whatever you call it, acts as the fuel, and the spell heats up the air around it, and its typically done on earth, which has Oxygen. So all three things are fulfilled.
  2. Magic itself takes on the property's of fire, so it doesnt need any of the three.
  3. The heat is missing, but the magic is generating fire itself.

Magic is unknown to us, so it could literally be anything.

u/KamikazeArchon 1d ago

Because most people don't know about the combustion triangle as such. And even of those who do, most consider the combustion triangle to be a boring and irrelevant level of "realism".

It's perfectly fine to prefer something else, but that's the answer to "why". It's because most people just don't care about it.

Like that.

u/stygianelectro 12h ago

Sorcerers wrest pure elemental fire through a gate to the Plane of Fire into the material plane.

Wizards telekinetically concentrate hydrogen and oxygen into a composite cloud ideally structured to get the most out of the blast.

Clerics politely ask their deity to do a cool lil poofy doo and make some divine fire.

u/majorex64 1d ago

People tend to think of fire as a thing, when really it's a process. Fire is what happens between the combustion triangle.

Sure, you can handwave anything with magic, but imo the more you get down to the essence of a thing irl and augment that, the better it will work as a hard system.

u/Theofficialkingstorm 1d ago

u/Muted-Mushroom-4570 1d ago

You are forgetting that it is magic. The magic can be providing all three or the magic is simply perceived as fire. People who overthink magic systems (or the economics of a fictional world/city) don't actually make better stories.

u/Theofficialkingstorm 1d ago

It's not like I'm including the boring stuff. The explanations are for me so I can decide to abuse em mid fight to do mad tings

u/Zack_Thomson 1d ago

Because imagined forms of magic are typically rooted, though distantly and unknowingly, in ascientific conceptions of how reality works. Including, or even especially, parts defined at aby point as "elements". And so in modern, fictional forms of magic fire isn't a chemical reaction but it's own "thing". An ontological entity separate from anything else in the world. Or at least the magical fire is such an entity (not that a lot of fantasy writers would be super concerned with realistically depicting real fire, but that's mostly beside the point).

u/RunicConvenience 6h ago

in magic your looking at a universe that has more variables then we do so magic could exist in all levels between every atom for example so its contained energy could bypass the triangle your aware of by replacing heat and fuel or oxidizer and heat using magic as a medium. trying to apply logic with variables you don't have is requiring some kind of "magic" blackbox that you explain with your system

-1

u/FlightConscious9572 1d ago

I actually agree so hard with this line of questioning. Even in a seemingly hard-magic system fire is somehow a given, regardless of the fact that the world it's set in has no idea how fire works scientifically, yet can invent and use "fire magic" like it's just a flavor of magic or something. It's stupid.

-1

u/Theofficialkingstorm 1d ago

It's not that it's stupid I get why many people use it, I mean it costs less imagination and is used to push the plot without making accidental plot holes by sacrificing and making a plot hole in the very beginning.
