From Ardrana

Glamdring was a human assassin who briefly traveled with Tobias Proudfoot and his companions. Following their first mission into the Caves of Chaos, it was revealed by Thorin, a paladin, that he harbored evil intent. Before his intentions were revealed, he attacked the party, then attempted to flee. He was cut down by arrows before getting very far.

Glamdring was a PC played by Sean Hayden.
