Most of the energy GREED possesses is in the high heaven realm, not the Tyrant realm. As a smart and greedy demon, it knows not to put its eggs in one basket. And as a double agent, it knows not to put most of its eggs on a sinking ship.
Most importantly, GREED had to put a clone in a location where its true boss could meet with it. So GREED was in the abyss of the high heaven realm when someone came to see it.
GREED, an ocean of sickly green energy, was roaming the depths of the abyss when this person appeared silently beside it. There was no aura from the visitor. It was almost as if they were a dead object or a hologram. But GREED saw this person and shivered.
If GREED had legs and could bow, it would. It couldn't, so it had to make do with speaking respectfully, "Welcome, Monarch High Heaven."
