I did this earlier this year, my old D&D group basically disintegrated after three sessions... Something about the DM having a workshift change from what I remember.

I've recently started attending a new group run by an old friend, hence I thought I'd remake Karfor for the game (some of the previous DM's homebrew stats didn't really work.) And as such I figured I'd update his artwork. He seems to have gotten a bit more wretched in the intervening years! Besides I couldn't let his backstory go to waste...

Found as a baby dragonborn by traveling traders he was raised like the other livestock and taught to protect the caravans and people there in. Not until he was in his teens did he learn to speak common, up until that point all he could say was "Car Four!" hence where he got his name.
Things came to a turning point when the caravan leaders daughter wandered into the swamp lands, the same lands that 16 cycles ago they had found Karf, and was attacked by a monstrous crocodile... No ones exactly sure what happened that day but according to the travellers Karf said something in Draconic, his eye's changed from they're natural blue colour to a purple and the crocodile seemed to to transform to crystals and shatter.
After that day the travellers gave Karf access to any books and knowledge he requested, his thirst for both an explanation and a way to control his abilities drove him... He learned of Wild Magics, gods of chaos and his Draconic heritage. He also recovered a lot of the crocodile skeleton learning it could be used as a focus for his spells. When he reached his 23rd cycle the caravan leader told him that he was free to pursue his curiosity... She still had affection for him.
