Spoken like someone who's never brought back old rivals from the village they lived in, or people they scammed out of money while they were carousing the streets, or an old flame they had back but had to call off for whatever reason. Or, y'know, settle disputes in a land they were exiled from for whatever reasonI don't expect characters to have backstories. A character's story begins at 1st level. Whatever he/she did before that is irrelevant.
Backstories are delightful to drag out at times. Give the other players a chance to narrate details of a story to the other players and hella engages them with stuff they were involved in
