Dunderhaven

Dunderhaven is a town in the Kingdom of Evenhold on the world of Eamon that features in The Lair of the Minotaur by Donald Brown. As mentioned in the adventure's introduction, the adventurer's partner unsuccessfully attempts to burgle Dunderhaven's nearby castle and winds up a prisoner of the castle's inhabitants. Beneath the castle is an entrance to the lair of the Minotaur.

Dunderhaven is probably just a short distance north of Evenhold and is near a southward-flowing river, likely the Zyphur.
