Subterranean Meeting Hall

"As far as meetings go, we Blue vampires kinda don't. It's wild, right, being a tight-knit family, with all our work super intertwined, and we never see each other in the flesh. Typically, at least one person is astral projected in. In fact, most of the time, most of us are.
But when we do meet up, in our bodies or not, it's either at Spider's place in First, or this dingy, cold room hidden in the Third District sewers. I think it used to be an old utility room or something that got bricked off, but not before Huntsman scratched a teleportation rune into the stone floor. The only way in and out is teleporting to that one particular spot, and because the room is smaller than ten square feet, somebody couldn't really just guess their way into finding it, unless they wanted to risk accidentally merging their flesh and bone with brick and mortar.
There's not much to say about our little stone box, other than there's a table, three chairs, and a suspicious patch of mold in there, and that's about it. But it's a fine place to chat about things that we can't be overheard saying. Mission statuses, going over agent placement, giving assignments, things like that."
