Son of Kavian, Arn was always simple. His simplicity grew slowly into madness as the centuries passed, & now he is barely more than a feral beast. He lives in a hut in the swamps north of Kali with a pair of keepers, who tend his needs. At best, he is a simple child, at worst he is a savage monster.

He was kidnapped by the Indestructibles & is now one of Chryandemus's sacrifices.
