Outsider

This article contains information from the Warcraft RPG which is considered non-canon.

An outsider is at least partially composed of the essence (but not necessarily the material) of some plane other than Azeroth. Some creatures start out as some other type of creature and become outsiders when they attain a higher (or lower) state of spiritual existence. Native outsiders are native to Azeroth. They are creatures who have mortal ancestors or a strong connection to Azeroth and can be raised, reincarnated, or resurrected just as other living creatures can be.

Note: While outsider is used to describe a few specific races with similar characteristics, it does not mean that all are related.
