In the last D&D campaign I was in, I played two different characters, thanks to misplacing my character sheet. My first character was known as Sicarius Sexton, and was a gravedigger by trade and an Assassin by hobby.
Our quest to restore the elemental crystals took us to the peak of an erupting volcano, where a golem of lava and fire resided. After some negotiation, he offered the Fire Gem to us. Graciously, Sicarious reached out an willingly accepted the Gem.
|You foolish, foolish man.|
Due to the aforementioned loss of Sicarius's character sheet, the group of heroes would never see him again.
...that is, until the DM had him return as a minion of the main villain. He was quickly killed off.
