Bardoon

Bardoon is a massive caterpillar NPC found sleeping in Kingdom's Edge. He is incredibly long; his body can be seen in the background twisting through the cliff face. His tail is found to the southeast of his head; hitting it will make him chuckle. He does not mind the Knight striking his tail.

He is not a Wyrm, for he is too small and has too many limbs.

Bardoon climbed up to the top of Kingdom’s Edge to get away from bugs plagued by the Infection. He resists the light’s allure; it offers unity but also reduces a bug to instinct alone.

Location
Bardoon's head can be found in the north part of Kingdom's Edge. His tail is found near the Lifeblood Cocoon in this area.
