The Grishna are a group of arakkoa found at Grishnath and Raven's Wood in Blade's Edge Mountains. They are causing the ancients and protectors to become possessed by evil spirits. Already, they have caused the leafbeards and stonebarks to be inhabited by evil koi-koi spirits. Some of them carry strange, magical orbs, that, though they radiate evil, they also somehow feel as if they were connected to the natural world as well.
