The Humanoids, by technical definition, have "souls".
A "soul" is a multiversal phenomenon, where the consciousness itself (distinct from any particular thing to be conscious about) has mysterious origin from beyond the multiverse.
The Humanoid soul is sapient relating to speech and learning new ideas. The soul is a microcosm of the multiverse. The soul is complex with different levels. The level of the Material Plane, is the soul of a bodily aura, the ki. Even with a dead corpse, there is residual soul. This aspect of the soul what necromancy manipulates. But it is also the aspect of healing and wondrous stunts of ki. The ki pervades the elemental matter that the body is made out of. The Ethereal level of the soul is the self-identity, the aspect of the soul that can learn and grow, evolve and change. It is the magic of the artist, the visionary, the dedicated. It is the magical influence that exerts itself on the minds of others, the telepathy, the charm, the dreams, even an aura of ethereal telekinetic force, and manifests the influences of the Border Ethereal, Feywild and Shadowfell. The realm of ideals, thoughts, concepts, paradigms, symbols, archetypes, the information systems, where language takes on a life of its own, is the Astral Plane. This is the level of the soul that is immortal, the eternal self, the higher and better version of oneself. When a soul doing Good deeds gravitates toward the Celestial Planes, or the doing Evil deeds toward the Fiend Planes, it is ones own soul judging oneself accurately and precisely as part of the learning process. Among the Celestial, the soul is on the receiving end of ones own Good deeds, and among the Fiend, is on the receiving end of ones own Evil deeds. Like aligns like within the Astral Plane, and the soul force is part of this orientation.
The Humanoid soul is the nexus of this cosmic activity, and now the multiverse is starting to shift.
