Investigate the Cache of Madness and find the Mysterious Gurubashi Bijou.
Listen, friend. I don't know you, and you don't know me. But as long as we're both here, there's something Revilgaz wanted me to mention.
Maybe you're taking a stroll through this troll-infested jungle-ocalypse. Maybe you happen to find a priceless troll artifact or two. Maybe you bring it back to me and I accidentally leave behind a little present for ya'.
If you must know, it's for a project. And no, you can't ask what the project is.
