Seeing as there isn't any written information to be had, Ozzy decides to study each of the alters and draw what conclusions he can about the gods they represent and afterwards he grills the monk for additional information about any gods whose goals and gifts are not immediately obvious from what he saw downstairs.
(( From search I've found the following, there are eight gods:
Yo-drell of the Deep, whose alter is a boulder with 3 silvery cubes embedded in it.
Sha-calun the Everflame, whose alter is an eternal flame burning above a bowl.
Flux, whose alter is a font of mercury.
Parathun the Fleshsmith, whose alter is a constantly changing lump of flesh.
Scarlon the Mask, whose alter is a stone statue of a cloaked man wearing a bright white mask.
Blastel, whose alter is a live woman chained to the platform with a blade driven into her chest.
Nul-sheal the Green, whose alter is a tree with leaves of every element.
Shub-shalsheil of the Inksea, whose alter is an enormous book, it's pages filling with text and magical symbols as you watch.
I figure Sha-calun is for pyromaniacs, Parathun is for shapeshifters/transmuters, Shub is for runic scholars but the other are more vague to me. I guess Nul-sheal could be plant based, but the the leaves of every element might mean it's helpful with all elementals or maybe both. Blastel is confusing, though I'm guessing it has something to do with torture, or perhaps self-sacrifice. Yodrell might be an earth based elemental or just dealing with any sort of metal. Scarlon and Flux I'm kinda stumped on though Flux could be a god of chaos or simply change/movement.
Anyone may feel free to affirm or deny my conjecture based on your own experiences. ))
