There was a cat room below befallen I think. Now if this was it or a variation of this who knows.
The Befallen cat room you could unintentionally glitch into (and walk back out of) since it's directly behind the zone out line, but many zones have completely isolated rooms that you cannot get to unless you get summoned in. I did get to see some of them as a guide and did see one GM summon a player to one for a talking to.
I believe these rooms are mostly an artifact from the zone building tools used, they're usually at loc 0,0,0 and have writing on the wall that tells the designer where to warp to to enter the playspace. Image below isn't totally correct since (at least when I was one) guides couldn't warp to a location, GMs can though. Guides would just /summon stuck players/corpses to their own location.
