Alberich Ungart is a mountain dwarf, a cleric.

Why adventure in caverns? Well, I would be interested in finding about the history of the dwarves who lived in the caverns, as it is important to me so understand where I come from. I feel I could be useful to the other adventurers because I am a dwarf and a cleric, I might be able to help navigate caverns and keep everybody calm and alive.

As for working above ground… I am sensitive to the sunlight and prefer to work in shaded conditions.

Yes I think it’s possible there is a beholder within the caverns. As beholders have so many potential powers it makes me wonder if it is somehow related to where the dwarves might have gone that abandoned the caverns.
