The most extraordinary feature of the Wilderness is the ruin of Hive Tenebra. This necropolis was once the heart of Scintilla’s high culture and arts, built around a circle of stepped pyramids rising like enormous altars from the steaming jungles of Scintilla’s equator. The hive is now a titanic mass of wreckage gradually being reclaimed by the voracious jungle. The disaster that claimed Hive Tenebra along with millions of lives happened over eight centuries ago, and is thought by most to have been caused by a collapse of the geothermal heat sinks that provided it with power. There is no shortage of conspiracy theories about what “really” happened to the hive, however, ranging from ill-advised summonings of warp creatures to a deliberate act of sabotage by agents of the Imperium. Tales about its destruction are outnumbered only by stories about what might lurk in the ruins now: ravenous monsters, renegade nobles and hordes of hideous mutants ruled by a mighty deformed overlord. No one ventures close to Hive Tenebra with any regularity, and when they do they rarely penetrate into the collapsed interior of the hive where the foulest horrors are said to lurk.
