How to get there: Southwest of Dragonspire Isle. The southern beach leads inland to Duskhaven.
Duskhaven has blue slate roofs, a dragon square, a bank, general store, forge, kitchen and sheltered beds. The town is protected; the cave circuit is dangerous.
Each of the ten signed entrances leads to its own single-floor arena and one Black dragon. Different entrances never share a dragon. Players using the same entrance share that encounter.
Bring a boat for the crossing and return voyage. Follow the lamps through each cave bend to reach its surface ladder.
