Humans and monster creations.

Did twilight created human mortals from great spirit of light and monsters from great spirirt of darkness? There is a similarllity between humans and angels. Naming don't make them evolve and they don't require souls to awaken. Even lower level angels have name. Whereas monsters and daemons evolve when named and require souls to awaken into true demon lords.

It can also be said beings created from light get powerful with their own power whereas beings of darkness requires power of others.

Twilight being the divine ancestor and was created by veldanava to create other beings. It is possible he can manipulate great spirits like veldanava.
