A jumara, also known as a Worm, is a type of Shadowspawn that was created by Aginor sometime before or during the War of Power, currently found in the Blight. The jumara are merely a larval stage to an even more horrible and dangerous type of Shadowspawn, the nature of which is unknown; the jumara that currently plague the Blight will never transform.
Jumara are extremely dangerous. They appear as large worms and their movement makes a very loud squishing sound. Traveling in packs called Wormpacks, a person can hear jumara cry to one another, a chorus reedy and shrill. A jumara can kill a Myrrdraal; most of the terrifying creatures in the Blight will flee from a jumara, although jumara themselves are scared of that which lives in the high passes.
Jumara are very effective at overtaking prey. In order to survive an encounter with jumara, the Worm must be cut to pieces.
