The clan's only priest, he spends most of his time working the mine with everyone else. This means he's as burly as the rest of his mates. He can't swing a sword, but he can throw a punch. He can use a range of mining picks and tools, but would never wield these against somebody.
When working in the mine he wears safety gear like everyone else. At other times he wears simple loose-fitting shirt and trousers of white linen. For priestly work he wears ceremonial robes. He only has one set of these, so although he keeps them clean they look as though they're worn regularly. There are a few neat darns and mends.
It's not easy to tell behind the beard, but he wears a devotional symbol around his neck. The pendant was a present and he's fond of it.
The clan dwarves don't believe in their god as such; they merely accept that he's there, and there is an Understanding that he is probably as busy as they are, so best not take up too much of each other's time. Prayer is along the lines of a friendly chat (or a reproachful one, depending on circumstances). Inain is much more serious in his belief.
Inain's priestly duties are part-time: he performs weddings, funerals and other rituals as required, and helps out the clan archivists when an extra hand is needed with research or filing. His personal devotions include praying daily (a proper one, not a quick chat), fasting once a year and generally trying to live a good, harmless life.
His author really wants to name his place of origin Zwergenberg, for no other reason than dorkiness and/or aesthetics.
