what's funny is that fallen london isn't even the first to hsve a self destructive quest of this exact kind. in hellmoo, at the very heart of one of the most endgame areas, well past the bounds of what its wiki's spoiler policy was allowed to cover, was the Abyss. if one managed to track it down and get through all the ordeals involved in doing so, one could throw oneself into it. this deleted one's character, permanently.

seeking's actual innovation is weaving that into its ludonarrative and not just leaving it as "a technically-diegetic thing one could do if one wants to for some reason"
