The Peers of the Covenant of the Enlightened often perform elaborate and sometimes dangerous experiments using the most powerful technologies known to humanity. In order to ensure that they have all the assets required for such work they typically create labyrinthine and eccentric laboratories for themselves. It is not without some irony that these sprawling structures have been collectively named Promethean Complexes. Each complex is fully self-sufficient, using its own power source, fuel and other consumables, whatever they might be. More often than not, in order to contain explosions and noise as well as retaining complete anonymity and secrecy, they build on existing mineworks or new excavations to be contained largely underground, with esoteric and blunt looking iron and steel structures jutting out across the surface forming into a small estate or settlement.
