Damn that Yoshimo! The little prick set me up! And he was just getting good too . . .
Oh well, now I killed him because I HAD to, and I need to bring his heart back to the Temple of Ilmater. Can I get there from the Asylum or do I have to go ALL the way to the elven city?

It is worth 200,000 exp. Just throw it in your bag of holding and forget about it till you make it back to town.
