Life gets boring when all you can do is create things.

Eggyhead: I can build you physical bodies that you can possess, and you'll be able to do physical stuff.

Light: Nah, we’re good. Besides, in this form we’re immortal, and if we die, everything physical will be destroyed and everyone will be just like us, a bunch of spirits floating in the void.

If the body gets destroyed, you'll just go back into your spirit forms.

“…maybe.”

Heh, what if their true form is an orb, a orb emanating light and one completely dark

It would reuse my old concept
