For anyone who missed last sprint's update on the Weather Factory blog, we announced something we'd previously kept secret: the inclusion of an exquisite, fully-navigable map of the Mansus in-game, accessible via Dream.
Focus your unconsciousness correctly and you'll be able to enter the Mansus in several places, pulling through a smidgen of unfiltered Glory back with you to the world of the awake.
This isn't yet implemented in-game, but it will be present in the release version (and probably in the Explorer's Build, but NO PROMISES).
Full update on last sprint here, for those who're interested!
