As Shredder advances, sudenly she spots something unusual.

Two columns of stone, one on each side of the tunnel, around two feets wide and twenty five feets high. At first glance they looked normal, but closer observation revelas that they aren't actually part of the structure. They aren't cemented on the ground, nor do they touch the celing, and the pixie doesn't remember seeing any columns like that in the rest of the tunnel.

Closer observation fails ro reveal anything resembling a trap mechanism, but the columns seem to have slighly humanoid shapes in their forms.

Ooc:Only Shredder can see this. The other characters are more back and don't have darkvision, so they can't actually see anything.
