Ben and Theresa for Piper at first, though she might get teleported back to Chumi after he's been given some snazzy new wiggling ankle hair and the vigils stop chasing him. Chumi gets the vigils for now, then he'll stumble across that barbarian encampment Gerald and the Richards ran into. Maybe. Probably. Maybe I'll have Piper use the team-roll-call orb instead. It's still up in the air, for now!

Also, it was really Piper who abandoned Chumi, what with her inability to face horrific nightmare giants. I'm sure that if she was a little bit less of a wuss, they totally could have taken them on.
