From The Heretic Knowledge Vault
Joli is a priestess (of sorts) in the Temple of the Divine Dwarf in Rinkaiel. She enters the game when events in Rinkaiel point to the temple as hosting some decidedly un-temple-ish activities that attract the attention of the player characters, somewhat reluctantly as they'd really rather give the place a wide berth. Her father, Reverend Orpiment, is the high priest there, and may have more to do with those unsavory activities than Joli does; at least he seems to be aware that they're going on, while Joli blithely goes about her business as though the Temple of the Divine Dwarf is a real religious place.
Joli basically gets along with most of the player characters who cross her path (Layla and entourage), and indeed calls on them for help when events at the temple go off the rails. However, "help" like theirs is something she really doesn't need, as the body count (e.g. the decapitation of the unfortunate Brother Roscoe by one of the temple's curiously lethal security devices) and magical damage to the place increase immediately when the "helpers" arrive. Cause and effect? Random chance? Who knows? Anyway, she's still there waiting, in case the action in the game returns to the temple, which doesn't seem unlikely.
