Going back a bit here - D+D module Tomb of Horrors (if you plan on playing it and dont want a spoiler stop reading).....
Basically there is a chance a charachter gets his soul drained by the demilich and subsequently destroyed forever. Anyone who has played old A D+D will appreciate how long it takes for a friend of yours to build a char all the way to a level 17 mage - he wasnt a happy bunny... In the interests of friendship and the ongoing campaign, I cost the group big time in wishes/cash/favours etc to quest for a way of bringing him back - so I was a big softy in the end
