With a cleric of Rogar in the making I thought it would be a good idea to solidify the specifics of the god and granted cleric abilities. Plus, it's just a good idea to have that done anyway. The only bit of information about the deity on the wiki that I know of is below:
The Dwarves worship Rogar, a one-eyed aspect of the Ruler. Legend states that Rogar lost his eye fighting evil gods on the day the Dwarven citadels fell, and if not for his courage and strength of arms evil hordes would have been released upon E’n to wipe the Dwarven race from it. Each Clan depicts Rogar differently, but all of them emphasize his role as a craftsman and his skill with an axe.
