Cell for Dead Void Creatures

The Cell for Dead "Void Creatures" is a test cell in the game files of Fallout: New Vegas.

Layout
A simple empty metal room with no doors or lighting. There are four other identical rooms which must be no-clipped into to access, and one larger, equally empty room. And one other room which has 3 NPCs, which could be Lily the Nightkin when she was a human and her two grandchildren.

Appearances
Cell for Dead "Void Creatures" appears in the game files of Fallout: New Vegas but should obviously not be considered canon due to it being a test cell of the developers.
