Hinichi are a wolf like race.
The art shows them to have 3 fingers and a thumb on their hands and be digigrade. The middle two human fingers seem to be merged together.
They are Christian. The usual symbol is a Christian symbol with a wolf lounging at the bottom. They do not like people cussing using Christian terms.
