Neither Lilly nor Leon actually know what the room is. Between memories both past and recent, they say that there's not actually an entrance down or out around the end where some fragmentary records say it should be. Lilly's guess, as primary past memory haver, is that Mrs. and Mr. Steiner probably just tore up some floorboards, put tarps down in an impromptu hole, and called that the emergency basement if it exists.<br/><br/>The whole being attacked sooner than expected thing means that it could entirely be a planned thing and they just didn't note down where it was going to be stored until then. And it's less older gen tech as ruggedized stuff that was supposed to be part of the same kit installed into a home. Corp money making by offloading necessary stuff into other pieces, selling them all, and justifying it by making the stuff more lasting.<br/><br/>As for the water pump room, it stayed unvisited because it was for the simple reason that it was entirely for outside the home things and in addition to not using those, it would also mean extra upkeep all around the perimeter and probably having to find and fix new problems once the system was up and pumping again. That would get the pool usable again, though.<br/><br/>As for the garage, it has mostly serving stuff for large parties or at least one hell of a Thanksgiving. Plates, settings, chafing dishes, all that kind of stuff. There's also a box that has some cards, dice, and game pieces.
