The southeastern reaches of the Far Forest still harbor a mysterious evil that spews forth cloakers and choas beasts from underground caverns. Those who have dared to enter these natural caves say they stretch for miles underground, and are guarded by vargouilles. Perhaps a deepspawn lairs therein, or perhaps a portal disgorges these monsters from elsewhere.
Named for an elf adventurer, Taerym, who met his death under persistant cloaker attacks while trying to battle his way into the caverns and identify what evil laired there, Taerymdoom remains a mystery - but it's a peril known to have claimed a Zhentarum exploring party and at least one band of adventurers, the Darkblades of Esmeltaran. Worse yet, its reach and boldness seems to be spreading.
