Dreamer's Rock is a small chamber beyond the Screaming Gully. The sleeping night elf druid, Naralex lies in repose in this chamber of the Wailing Caverns. His dreams have turned into nightmares, the monsters therein spilling out into the waking world. His disciples have become corrupted by his nightmare, led by the Fanglords. After the Fanglords have been defeated, the Disciple of Naralex near the entrace to the Caverns, goes to Dreamer's Rock to attempt to wake the dreamer. However, many dreadful monsters come to put a stop to the disciple's efforts, worst of which is Mutanus the Devourer.
