- Labyrinth: An intricate combination of paths or passages in which it is difficult to find one's way or to reach the exit. Any confusingly intricate state of things or events; a bewildering complex.
The Labyrinths of the Nephandi are twisted, alien things built in the Deep Umbra by equally horrific masters. The Nephandi target Nodes which anchor the Labyrinths just barely enough to stop them from tumbling farther into the Umbra. As it is, they are barely sane and filled with terrifying angles and howling praises to Entropy.
