John finds a piece of one of Rosalia's broken arrows and pokes around in the liquifying remains of a beetle. A small hard object catches his attention. Pushing it out of the sludge and rolling it around a bit reveals it to be what appears to be a tiny human skull no bigger than a thumbnail. The thing quickly crumbles however before John can point it out to anyone else.
The search for Grok is brief. Starting with a blood trail, the party backtracks. The further they go, the blacker the blood gets before it is no different from the black sludge witnessed coming from the other tainted beasts. As the party approaches the cliff where the first beetle battle occured, the sharper eyed members catch sight of a dark, low shape at the base of the cliff.
OOC: You are all at the edge of Scrag's darkvision (roughly 90' away, I believe), having stopped at the first sign of possibly finding Grok, with the chance to do something before going any closer. What's everybody doing?
