Gregorius then heads towards the remains of a ruined building on the eastern side of the central courtyard. Close to, Stephen can see within it a broad staircase leading downwards, made of the same limestone as much of the rest of the covenant. Following the staircase down, you come to a reasonably sized cavern with three doors and a passage way leading off it. Gregorius opens the closest door on the left, saying:
"Most of the covenant's laboratories are down here, as the aura is more constant than on the surface, and at least as strong. This is the only spare laboratory we have set up at the moment."
The lab looks to be a fairly standard laboratory, although the equipment is of a good quality, and it's warmer than you'd expect given the season - although come to think of it, that could be said of the house as well.
"This room opposite used to be the infirmary, until we got its building constructed. We're planning to put another laboratory in there soon. This room at the end is the Sanctum and laboratory of Tasia of Guernicus, the covenant's leader. As I mentioned earlier, she's away from the covenant at the moment, so I can't introduce you."
Gregorius turns down the passageway, which has a door on the right, and another staircase leading down it on the left.
"Through the door is my own laboratory, although I spend most of my time in the main house." He seems inclined to leave it at that unless Stephen expresses a particular interest.
"There's a second level of the caves beneath this one," as you descend the staircase to a second smaller cave, with some more doors leaving off it. "The door on the right is Fray's laboratory."
[OOC: Depending on where this thread is in the timeline, there are also a number of entrances blocked off with rubble, or a long room with two entrances and a river flowing alongside it and a further staircase leading down.]
"That largely concludes the tour."
