== Sedna ==
The furthest known object of note in the outer system. Sedna was home to a strange and little-known but powerful Xenos race that terrorised the Sol System during the Age of Strife. It was apparently not a planet, as it's referred in records as the "false/nemesis planet", so it was probably a [[World Engine]]-like ship (meaning the 'little-known' race might actually be [[Necrons|'Crons]]). It was site of the Sedna Campaign, the last major battle in the system until the Horus Heresy, in which eight full Legions were unleashed against the xenos and wiped them out with great effort and an unknown psychic weapon. Sedna has since been forgotten in modern times and it's uncertain if it still exists.
