According to myth, the diverse species of the Convergence derives from the dead origin planet, Ertfiil, although it is so far in the past, before the Time of Forgetting, that no one really knows the truth. The mythologies also tell of other diverse origins for many of the outer worlds, although, due to the assimilating technology of the Memories, the actual cultural and DNA origins of these people are shrouded in mystery. The Memories and the paths between the worlds was re-discovered 10,000 years ago after the Time of Forgetting.
