[Taqwus]

Bug or oddity: There's a magical site ("House of Strange Lights" or something like that) which appears to have the same "enter to summon void monsters" as R'lyeh's Void Gate. This House appears on land... yet water-only things such as the Dwellers of the Deep can appear. Resulting battles use the terrain of the surrounding province.
Perhaps the aquatic-only should be disabled?
