Stellar Pyramids of the Southern Skies

The Stellar Pyramids of the South Skies are the destination of many a Mage-Priest's pilgrimage. To meditate in their shadow is to gain an understanding of divination surpassed only by the Old Ones themselves. Over the millennia, the pyramids have been the target of a great many Dark Elf raids, the Sorceresses intent upon reading the entrails of sacrificed prisoners in order to divine their own futures. None have liked what they have seen, for in every case the readings have foreseen a swift death at the hands of the vengeful Lizardmen.
