Dungeons & Dragons of the Nentir Vale
Temple of Yellow Skulls
The ruins of an evil shrine stand in the middle of these desolate hills. Legend tells that a rakshasa prince summoned demons to this place and bound them to his service by imprisoning their vital essences in gold-plated human skulls. None of these have yet been recovered from the ruins, but the story persists. Deep caverns beneath the ruins lead all the way down to the Underdark, and from time to time dangerous monsters of the deep places emerge here and prowl the nearby lands.
