Blessed Kin. Shadekin are eyeless Kin, are composed partially of shadow. They can disappear into shadows and teleport from one shadow to another.
The Blessing of one Kin will pass through its psychic connection to its family members. Thus, almost all Shadekin are found in groups. They are in constant telepathic contact, with each other, and coordinate their actions perfectly, acting as if they were a single entity. See the entry for the Kin for more.
