Voodoo Dues

My list is shortening, but there are still people who owe me. Next, we have Maury "Club Foot" Wilkins, Jon-Jon the Crow, and Chucky "Ten Thumbs." These scurvy dogs' debts are months outstanding and I thought they skipped town to avoid paying up! Later, I heard they're cursed and bewitched and now wander the jungle ruins. But I don't care what their fate is - I want what's mine! They're at the Ruins of Aboraz and the Ruins of Jubuwal, northeast of here. Find them, and collect.
