The Bovo Popuo

[Havard]

When the dwarves first arrived in the north, a dark race now only reffered to as the Bovo Popuo (dwarven for "The people from before") lived in the mountains. It is believed that the dwarves wiped out this entire race, but that their spirits still linger in dark places deep below the mountains.

Any thoughts to what race this might be?
