51-8: Coil is the designation given to an enormous verge god that once inhabited the edges of known space in the Ealdremen System. So fathomless was 51-8: Coil, according to the few remaining direct contact reports, that the verge god's very body was an "infinite and boundless coil of stars, scales, and eyes, all of which burned like embers in the god's totality". Because of 51-8: Coil's presence, Ealdremen astronomers even during the Millennial Calm's height of power struggled to chart space beyond Ealdremen's reaches — resulting in major astral bodies such as Rolokus and Eurtune or planets such as Nethere going undiscovered for thousands of years after the invention of space travel.
