Sven

Sven appears to be Questor's friend. Questor has lend Sven 10 gold coins, something that seems uncharacteristic from our gold hungry Elf. Sven is referenced in The Cathedral of Flame where Questor says to his companions to let Sven know he can keep the borrowed coins if Questor doesn't make it out alive. Questor then mentions to forget it, as Sven will figure it out for himself.
