Replacement

Three lame character backgrounds are the brother of a dead adventurer who is the same in every regard, the orphan who cares for nothing and no one, and the amnesiac.

Replacement characters are either the result of a very low level character death before the player managed to accomplish what they wanted to do with the character or the result of high lethality games where making a brand new character every session is a pain. The orphan tends to result from a different kind of campaign abuse, where the player has grown tired of family members being put in danger and kidnapped more often than Princess Peach. And the amnesiac is someone who has just given up with writing backgrounds altogether.
