New comic's up. Since the Silverfronds and Everwood crew were talking a bit about Jack, we're seeing what him and his buddies are up to now. Yo-Lee has sensed Mortaridar's arrival on the plane, as did Wesley, but neither of them know it's him they were sensing. It looks like most of the Clerics (and Outsiders who happen to be on Manjulias) have sensed his arrival.

Why don't they just ask her to Greater Teleport the group closer?
Teleporting can only take you to places you've already been, or at least seen or studied. Yo-Lee hasn't been that many places on Manjulias, so her teleporting options are pretty limited. The only reason she was able to teleport to that area where she stole those items was because she has been called there before during one of her Succubus contracts.
