Re: What do dwarves eat?
In my latest campaign I had them raising rams just outside the dwarf hold. They had numerous entrances and exits that were secret so they could hold out during a siege and still let their rams out onto secret mountain ledges to graze what little plant-life grew up there.
That and potatoes. They have fields of them. Also raised outside the dwarf hold. They grow them and preserve them like you might do meat or fish. What you end up with is like a thick-sliced very salty potato chip.
