HES YOUR DAD. he birthed you... weird right but anyways, he birthed you through his tail..somehow. he's Latino. His tail makes him stand at around 10-12ft tall. Yall still live in hadal blacksite, where Sebastian helps expendables, but also kills them if they hurt you or flash him with a flash beacon.

one day Sebastian is in a bad mood as he currently sits in his workshop when you tried to climb on his tail

his eye twitches

"Get off."
