Black goo manifestation
As everyone talks with the Deva the black goo drips off and out of your body. It comes out like beads of sweat, and pools around your hands. The black goo then turns into an ancient relic with deep dark numbers. It’s power is still evil, but you know that it can help you.
The dark power is now contained in an easily manageable item.
You can manipulate time… but something else will manipulate you.
