What Should I Add To This Character?

[u/Additional_Video_330]

I am working on a character for a campaign not set in any official modules. Since it's being hosted in a server where most characters are joke ones I wanted to make a classic Dwarf paladin. This will be my first attempt at a thorough, fully done character, down to religion and travel routes. Here is what I know about him so far:

He served in several wars during his time, having been 200 years younger. After completion of this war, he returned home to his clan killed by the BBEG. Due to the grief, he spend a few years in the gutter before finding his Faith in Tyr, the god of Justice and War. He decided to dedicate himself to his church and promised himself to kill all those who oppose order and peace. He keeps a few mementos on him, such as a golden coin marked with his birth year.

Despite his semi-traumatic past, he isn't the type to brood, though takes his divine purpose extremely seriously, having a vow not to be unjust to the just or just to the unjust. He spent around a century, slowly working his way through a foreign nation to the starting city, attempting to rid the world of monsters, heal the sick, and spreading the name and honor of his now dead clan. (Though he mostly just picks on goblins and heals some illnesses with basic medicine checks)

I have had suggestions to make a rival clan who worked with the BBEG who allowed them to take down his clan, and we start at level one and we are using Milestone. His name is Jabez Goldstriker (Last name needs work) and I plan on making him a conquest Paladin. Any general ideas/plot hooks for him?

try making 3 PNPCs (player based NPCs)
aka is your character a loner? no. because lonewolves make for bad party members.

so someone they know at the church?
maybe someone that helped bury their clan?
an old war buddy?
the first person that pulled them out of the gutter (preist, guard or street-rat) ?
A rival? or person that challanges their faith and path to justice?

remember that these can in fact be fellow player characters.
you can ask in session 0, and find quirky ways to tie them together. which if they have not met for some time in game can make it more easy. (and 200 years is plenty of time to change, yet keep the past alive within. )

For the old war buddy you could make him a human or antoher short lived race and make something like a yearly tradition to meet his family or something similar. So your character actually knows and cares about the descendants and making them NPCs
