Maybe it should be a karma portal location with a huge mother f***ing bada$$ concrete X (Roman Numerals..) that is in the center of the area...
*gasp* it could be a karma portal location that comes out of Coord. 010 !!!!
Then the karma coordinates could be "xxx" (which would actually mean 30, so scratch that)..or "ten" or "dzi" (Polish abbr. for ten? Google Translate's work, not mine)
The karma portal leading to the room could be shattering the concrete X in one part, and the room could have a bunch of early sketches and plans and blueprints for the first Submachine games
Too much extrapolation there, I know..but it would be cool
