If the long ventured funny theory would be true that Shadowheart could be a prior devotee of Selune (?) turned around by brainwashing, what would Selune say to lightning damage? As I understand it, the gods play an important role for Clerics because the latter's power comes more directly from the gods than say, those of Wizards or Sorcerers or Paladins.
It's more a case of "what do the other gods say about having their schtick purloined?"
If I can read in a straight line this time, Selune gets Knowledge and Life. Plus Twilight, which is pretty ubiquitous these days on account of being so overpowered. Selune is a powergamer!
