Perytons

Perytons (ペリュトン, Peryuton) are the typical summons of Getsugakure summoning ninja, being the only summons known to be officially aligned with the village. They live within the Land of the Moon, and seem to exclusively inhabit Yamiyo, a sheltered and highly inaccessible valley cloaked in darkness. They are green creatures in the shape of animals with the forelegs, torso and head of fanged stags, and the wings and tails of great eagles.
