Moebius

Moebius is the capital tomb of the Nekthyst dynasty, a hyperspace maze of crypts whose layout rearranges so that no two journeys through it are the same. Its passages are therefore not fixed: a route taken once cannot be relied upon to exist again.

Kill-teams of the Deathwatch have encountered this property at first hand and have learned to treat it as a defining hazard of the tomb. Movement within Moebius cannot be planned from earlier passage, since each journey follows a different arrangement of the crypts.

Moebius is a less frequently cited name than Solemnace or Mandragora. This relative obscurity reflects the character of the site rather than any lack of importance, for the Nekthyst dynasty conceals itself within the tomb’s shifting geometry.
