Magnus is keeping a wary eye on the mysterious trap door he accidentally opened, but it's evident he doesn't trust it. "A look around the known paths first seems more sensible than running the place like a labyrinth from the old tales," he notes.
Lining up as Hastali suggested, the party ventures down the stairs past the door Mart just opened. It is, perhaps unsurprisingly, quiet save for the slap and scraping of their leather soles against the wrought stone under their feet. The stairwell takes them slightly past the pile of bones at the bottom. They appear to be human; other partial skeletons litter the chamber besides, tangled with knots of old spider webbing.
The chamber is wide, somewhat resembling the previous chamber with the text inlaid across the floor. This one, however, has no such text carved into the floor and its original purpose is, at first glance, unclear. An initial assessment of the chamber will reveal two immediate details: there is another heavy wooden door set in the wall straight across from the stairwell, and a second set in the wall to the right.
The first door is notable for being the evident site of a recent scuffle, with a familiar-looking giant spider laying curled up not four feet away from it. A flamberge style dagger protrudes from between its mandibles; the beast is quite apparently dead.
The dust in front of the other door is, by comparison, relatively undisturbed.
Magnus trails down the stairs behind the other two, peering into the gloom past the torchlight. Upon catching sight of the tableau near the far door, he exclaims: "What in the abrogated city of dust did THAT?"
OOC:
The torch begins to burn low again; Mart (or someone else if he's not available for it) will need to light the next torch soon to keep the expedition going.
GM Note: Magnus's reaction is meant to land after the party takes stock of the room's content and isn't intended to pre-empt whatever the two PCs would be doing during the initial examination of the area.
