From '''785''' to '''795'''.[[M41]] the [[Masque of the Dreaming Shadow]] would engage in a decade-long campaign to purge [[Necron]]s from the tomb world of [[Maedrax]]{{Fn|7e}}, following a forced retreat of [[Ulthwé]] at the hands of the [[Blood Angel]]s in '''783'''.[[M41]].{{Fn|14g}}

After the collapse of a [[Necron]] [[Dolmen Gate]] allows a horde of [[Khorne]] [[Daemons]] to spill into the [[Webway]], the [[Masque of the Veiled Path]] divert diverts the Daemons to [[Magnor Prime]] which they had defended nearly a millennium prior, the .

[[File:PortDem.jpg|thumb|200px|the The [[Masque of the Midnight Sorrow]] fights beside [[Eldrad]] on [[Coheria]].{{Fn|42}}]]In the closing days of the [[M41|41st Millennium]], the [[Masque of the Midnight Sorrow]], through the [[Death Jester]] known as [[Inriam|Inriam's Shade]], worked with [[Eldrad Ulthran]] of [[Ulthwé]] to bring about an early awakening of [[Ynnead]]. They planned to flood the ''[[carrecenad]]'' surface of [[Coheria]] with the souls of two warhosts (one of Ulthwé and one of [[Saim-Hann]]) while the crystalised [[Farseer]]s of Ulthwé's [[Dome of Crystal Seers]] would serve as conduits to the [[Infinity Circuit]]s of every craftworld across the galaxy, in order to temporarily join the spirits of all craftworlds into one place in [[Reality]]. This would create a psychic beacon magnitudes brighter than the [[Astronomican]] which could guide Ynnead's abstract soul from the immaterium into reality. The consequences of this plan which would not be without incident, as fleets in [[Warp Travel]] across the galaxy would be thrown off course and every [[Craftworld]] would be left temporarily as inoperable dark husks as their Infinity Circuits would be left bare awaiting Ynnead's intervention. However, the [[Battle of Port Demesnus]] foiled the plan when [[Deathwatch]] agents employed a [[Stasis Bomb|stasis bomb]], an act which defied farsight, and the newly formed skeins of fate revealed Ulthwé's destruction.
