Jim John

Genetic son of a Warrior adventurer who protected the people from the fay den forrest and JAX the leader of the fairies. his father jimson John turned a drunkard after Jims birth killed his mother (as in common for children of the fey) she was a strong fighter who was ambushed and defeated by fairies but her strength seemed favourable to the leader JAX and he let her live after planting seed in her sleep. She later escaped and returned to the small village leading to the birth of jim.
Jim was later kidnapped at age five a Hag thought him valuable to the fairies but only if he was a strong warrior so decided to speed up his aging while decreasing her own (also with the help of other children she stole), however when Grax arrived she fled after seeing the creature murder one of her captive children in a flash before leaving else where, Jim was under an illusion that made the place seem like a magic ginger bread house however his near unbeatable jaw was no match to the metal and after the witches reinforcing magic wore off he escaped his cage and headed home to find his father in a worce state then when he left. The witch also sealed off his magic so until a skilled witch removes the curse he will be unable to cast pixie magic.
Jim is a Pixie but similar to JAX however he developed unusal size as his growth was unhindered due to his mother being born and raised in mevlova and smilled apon by anypixouse, he will never grow wings his invisibility is sealed and he could one day grow to out power JAX and become the new leader of the faries.
Jax has a chilhood chrush on one of the villige girls, he was always a very happy boy and loved by almost all the village, kids near fay den are often switched with fey and people are fine with odd children thinking (odly sharp teeth is hardly an issue compared to other children who returned with tails, or could see with no eyes), he has yet to develop his magic and will be unable to due so until the remove curse spell or dispell magic is cast apon him.
party encounters another of JAX's children who also has sharp teeth bit is much smaller like a gnome with wings (where JAX is closer to a dwarf)- JAXIE head of patrols is put on a mission to avenge simon after he was slaughterd, they see Jim as competition to be removed but focus on the more dangurouse enemies as they have been trained, (Jaxie is a pixie but loves to talk too much, they will use there invisibilite to there advantage and have rouge features attacking once "with sneak attack most often" however they lack the poision jax has (JAX stat block but 4d6 peircing) they also travled alone) they are they will leave if they think they are going to die and call apon there father for help if the party dont leave the forrest before then they will be in deep shit.
