With Dawnguard installed, more enemies appear, including chaurus hunters and falmer warmongers. Gloomreach is home to a band of the sightless Falmer and their domesticated insectoid chaurus. The roof of the caverns are covered with a glowing bluish substance. The cave is lit by an eerie greenish blue lighting and glowing blue tendrils protrude from the walls and reach down from the ceiling. Gloomreach is unlike most other cave systems, as the explorer discovers shortly after entering. It is divided into two sections: Gloomreach Cavern and Gloomreach Hive.
