Deep Dwarf Rush
This deep is well known among dwarven scholars for its incredibly rich silver mine as well as for being one of the wealthiest cities in all Derwidia. It is so famous that many non-dwarves have also heard of it, perhaps told of it wistfully by a dwarf deep in his cups.
Whether or not this particular deep is truly Duargrad remains to be seen. Nontheless, it has attracted all manner of adventurers, scoundrels, opportunists, and mercenaries from all the Known World. Much to the irritation of the Reclaimers who tried in vain to keep its discovery a secret.
