Infinitude Gems

The Infinitude Gems hold power hitherto undreamt of. One cannot hold one in their hand without already being a very powerful being as the gems are so strong they would kill any mere mortal. Still, you must have great power to wield them when they're contained inside of something (such as The Eye, The Scepter, The Tessaract, Natalie Portman, The Orb, or The Gobbler). Very few beings in the universe can unlock their full power.
