Clerics in game are largely not hugely developed and the brief blurb which describes the various gods in character creation is insufficient and rudimentary.

Clerics perhaps have some of the most strictures on behaviors and actions that might lead them to fall out of favor with their god but there is none of that here.

Shadowheart’s revelation aren’t hugely remarkable in light of the other characters backstories, which are all pretty edgy.

It is obvious she is a cleric of a shadow deity from the get go. What is not obvious at all is when Tav is.

Absolutely no one comments on Tav being a cleric, and it rarely is brought up at all. I find this too bad, since it seems to be a interesting way to develop relationships between the various characters.
