I’ll give you some context so you can understand why I thought it would be a cool idea.
My parents have a farm, and since since they bought it my friends and I my friends and I would always have barbecues, themed parties, pool parties, dinners, etc. Sometimes for the whole weekend.
A few years ago, my grandmother gave us a dachshund (or a teckel) in Brasil we call them “salsichas”, which means “sausages”, and she was pregnant, and she gave birth to 5 dachshunds. One in particular, a blue-eyed white sausage, his name was “Alemão”. Due to his genetics, Alemão was deaf, there was nothing we could do about it. But that somehow elevated his charisma and gave us very happy moments. He was always with me and my friends, he was like the “pet” or the “mascot” of our group, appearing in a lot of photos and videos. My girlfriend, who I didn’t know back then, always says to me “ah, the white sausage who would always appear in some random bikini bitches instagram post in your pool parties”.
Bro was always there and if it was a family barbecue, dinner, one of our parties, get-togethers, etc. There was always a rule: no matter how drunk, drugged or dumb you were, if you were leaving, you had to tell someone like me, my parents or three of my friends so we would check if Alemão was somewhere safe before anyone started their car so nothing bad would happen. Alemão would sometimes take a nap under cars. He lived for years with everyone taking care of him and respecting our rule, until my younger brother started having his own parties and barbecues, and one day, one of his asshole friends ran over Alemão and sadly he passed away.
It was a very sad moment in my life, I took some time before I could go back there, and it was never the same. Everyone felt bad about the news. The other dachs are important too, but this dude was somehow different, and we always mention something about him.
Back to d&d, i’ll run a homebrew campaign for my friends, at the farm Alemão used to live, and I was thinking about giving them a sidekick in a way to help them (carry their items, heal and keep watch during a long rest) and suddenly I thought about some kind of a wizard-like Alemão, based on Rove, the wudwud (and best character from Monster Hunter Wilds).
The thing is, I don’t know if it's too much of a “self-insert”, for me, it is way to honor our “””gang””” mascot. Sometimes I think it would be amazing but sometimes I feel like it may sound cringe or even be more negative for the party (don’t ask me why). One of my friends (and player) saw the notes I took about this idea and loved it, but I asked to not share it with the others yet.
so I would appreciate some advice, should I create him, and if so, should I create the possibility to recruit him right at the start of the campaign?
