GM: This a stairway up and down. The staff that are actually allowed in here no it is actually not useful and leads up and down to holographically disguised deathtraps, to be designed later. 21st century technology nasty-blasty-deathtraps. e.g. only intruders are likely to fall foul of these. Or drunk minions, but they don’t care about those.
