Nah, they're using magic, or psionics, or whatever the equivalent is on their world.
"Quiddity," as Thor explained it, roughly means "essence." it is their state of being. You don't see a god without their quiddity their divine essence, surrounding them. You don't see a mortal with it. Popcorn is has a yellow dweomer (or whatever the equivalent is on their world), not quiddity, because popcorn is not a god.
.... Presumably.
