Legends and recently unearth journals state that the location of the Blackrock Tomb, once lost after the Battle of the Twelve, is located behind a waterfall in the Downshipp Mountains. An unholy vault, dedicated to hostile foreign planar entities and their foul mother-goddesses, whose interior has never been mapped now beckons to the foolhardy, greedy and curious alike. Likewise, all attempts to map the interior are somehow foiled. Earlier recordings stated that some passages twist and turn on their own through tainted sorcery. The tomb is also believed to be the final resting place of the Paladins of the Righteous Scar, a fallen knighthood now lost as they sought to extinguish the evil with the vaults of the tomb itself.
Twin nude Mariliths form the archway and entrance, their many arms grasping their counterparts from some fifteen feet above the entrance’s floor. The tomb consists of several single corridors, all housing mirrors, duplicated down to the smallest detail and engraved with elaborate tactile knots carved into the woodwork into the stone by magic. Ghostly faces appear with in the mirrors, or sometimes colors but no shapes. Phantasmal sounds chime horrifically with armor and weapons scrapping across the stone floors of the tomb. Soon voices howl, then all is silent.

Sometimes the greatest discoveries are made by the foolhardy and the curious.... Chauncy the Satyr danced behind the waterfall, hoping to find some frolicsome nymphs, but what he found was...awesome.
After a long while admiring the nude maraliths and their huge assets, he did what any young satyr buck would do... He scaled their scales and began a minute inspection of the elaborate architectural frieze. A loving and careful inspection, rubbing his hands all over the smooth stone.
The giant maralith statues did not come to life (but what a way to die!) but Chauncy, as much by accident as anything else, at last spun one of the cleverly (or not so cleverly) concealed combination locks and opened the well-named secret chest. Guess what he found inside!"
