Nukarumi

Nukarumi were disembodied spirits of the Shadowlands creatures destroyed in a battle in the Shadowlands Marshes of Shinomen in the Great Hidden Forest, deep within the Shinomen Mori.

In that place, centuries ago, a Naga Pearl Magic was used to destroy the shadowlands beasts, and created the Shadowlands Marshes of Shinomen.

The Nukarimi were bounded to the marsh by powerful Naga wards, forever trapped within its confines. They manipulated the sludge to assume a crude and malleable physical form of sorts.
