Infectis Scar

The Infectis Scar is a deep lake in the blighted earth of the Eastern Plaguelands. Unlike the Pestilent Scar, which was a natural gorge (possibly a dried-up lake of some kind), the Infectis Scar is the result of dark magic. When his runesword was broken against the shield of a dwarf captain near Corin's Crossing, the death knight Marduk Blackpool discarded the blade and kept the hilt with him. The evil blade sunk into the earth creating a chasm. When the Cataclysm occurred, the chasm filled with water, creating the lake that exists today.
