Kinden examines the bodies, but the muck hinds any details except for the fact that all of them were human, and one of them at least was a gaurd of the above city before he had died. As for any sign of who created them, he can not tell. Kinden knows that such signs are rarely appearent to mundane means.
The bards song, even though a little inappropreate to the suroundings, fills those that listen with a sense of ease, it's light, humorous lerics bringing a smile to even the most earnest among you, with the common tune, well done as it is.

Shadowleaf, muttering prayers to his goddess, sees something in the wall to the east in the fading light spell ahead of him. It may be just an iregularity in the pattern of stone, or it may be that the surface seems slightly cleaner then the surounding stone.
Kinden, noticing the attention Shadowleaf is giving the wall, looks at it and notices the same iregularity.
