The feeling was more or less akin to passing through a portal. Well, perhaps because it was a portal.
We stepped into what looked like a...lobby? Yes; a lobby, or a lounge. A small room with two doors on the opposite wall, fitted with comfortable-looking chairs and tables. The room was circular, as if following the contour of a tree, although the size was nothing as wide as Alzeriya's circumference.
"The left one leads to the artifact room, and the right one is for the documents," the scribe explained, and we automatically steered to the right.
There was another seal on the door, and while the scribe was working on unsealing it, Amarein told me more about the place. "This is not the only place accessible from Alzeriya's gate," she told me. "Depending on the incantation, the door will bring us to different rooms."
"Oh? How fascinating!"
