Tavia nods, than snips her fingers to get anyone's attention. "There are stairs winding up and down the shaft. They bypass the levels as well as some extra chambers along the way to top and bottom. As the air makes quite a bit of sound, it will be hard to hear anyone ... or anything approach. Thus, make sure that you keep a good watch on your surroundings as well as your comrades. Maybe those in front or behind you spot something before you do!" She looks into the faces of the non-drow while getting her bow out, assembling in no-time. "Note that not everything down here is prey, or on the look for it. Some beasts, especially some undead spectres, may just have a look and return to their places if they see us pass their tombs by. That could change if you try to introduce them to the business ends of your weapons though. In any case, if you see me shoot, do not hesitate to follow suit." Adressing the yathrin, Tavia continues: "We will go upwards for two levels, then pass through a large hallway and a few corridors. They will lead us to one of the upper exits of the Tower. The entrance to the hallway is marked with this rune (she draws it into the dust and invites everyone to have a look, before erasing it with her foot again)."
Drawing her grayish cloak around her, the scouts sets off into the tunnel leading to the shaft.
