Tristan is the whole linch pin in Kyron's big plan to topple Barbello using the magic eater ("Get her? That's your big plan? Get her?")
Realizing he left the lizard somewhere upstairs and that Barbello could arrive at any time, Tristan races back to find the lizard before Baja gets to him and eats him. Thankfully Baja is distracted by chewing on the Xeph, who manifests veangefully from inside Baja's gullet. Baja is now able to levitate at will and is quite happy with his new floaty powerz.
Finding Raak Tristan is once again the big gun secret weapon and the new warlord's right hand man, feared by all in a just and righteous manner lest he smite them with the loss of their magic (A fate worse than death in high level D&D).
