The Aztec tradition practitioners are called nahualli (magic priests). They believes that every self-aware beings (even gods) share a portion of their soul with an animal spiritual twin, and their first task as initiates is to find theirs. Once they do, the spirit becomes a personal and individual mentor.
Any conjured spirit appear as an Aztec warrior or its animal form, honouring the duality of man and animal.
