The trees give way to an open spot in the forest. The ruin of some massive structure occupies the center of the clearing roughly 200 yards across. Stone, earth, and timbers lie in haphazard piles. Whoever laid waste to this keep was incredibly thorough. Bodies, marked with wounds from sword thrusts and still protruding arrows, lie everywhere around the keep and rubbish pile; they appear to have been stripped of their armor following the battle that occured here. The eerie silence of the forest extends into this open space.
Suddenly, a black orb with a 20ft radius, darker than any night rises 20ft from behind the rubbish pile. The pile is some 100 yards from the party.
Bhartus: you recognize the darkness as the product of divine magic (Darkness Spell). Something must lie at the center of the darkness.
Whitney: you recognize the darkness effect as the product of a spell commonly used by wizards of even meagre experience (Darkness spell). Somebody or something must lie at the center of the sphere. The floating is probably the result of magic as well , though you cannot be sure. (Telekinesis)
