At ttrpg, most dm's are adviced not to allow gale like backstory in to a table of normal low lvl characters, its very trouble prone and easily takes away fun and choice from others to make one character/player feel powerful.
Plenty of Discussion online, where dm asks other dms on the internet advice about this 15 yr old teen. Who has this character gale he wants to play. Its actually cursed lvl20 wizard, literal lover of gods and has friends who are lvl20, and worst of all. Can interact with these lvl20 friend characters at low lvl. Also has a lvl9 true ress scroll on him that the other players have to use on his character, if it dies too early or the world ends.
