Knox always lived near the big lake with his parents and his brother because the parents worked near that area.
Used to listen to stories that Granny Merry used to tell when he was a kid.
His father knew the Beast Tamer as an acquaintance, so he learned a bit about how he should deal with a big bad creature should he encounter one.
One night he went out in secret in a fishing trip with his brother, they were suddenly hit with unexpected waves and ended up falling off the boat. Knox washed up in the shore but his brother was nowhere to be found.
Knox still foolishly believes that his brother is somehow still alive and if he searches for him in the water he will find him someday.
He is quite tall and a bit lenky, his nails are naturally sharp but not enough to hurt anyone.
His hair is parted by his horns that swoop to the back of his head in a bit of a spiral.
He wears clothes that allow him to move more freely and that have warmer colors to contrast with his cool toned skin, so he does have a fashion sense.
I've wrote his backstory in more detail in a saved PDF document that i sent in my application channel in the discord.
