Obelisk (Earth-5192)

The Obelisk, called Diviner by Carter Hall, is a Thanagarian device that can telepathically interface with whoever touches it.

History
The couple Katar Hol and Chay Ara were in the possession of an Obelisk during their voyage which made them become trapped on Earth. After their deaths, it was entombed alongside their bodies at the Great Pyramid of Giza.

Thousands of years later, their Obelisk was found by archaeologist Joseph Gardner, who named it "the Diviner". By touching it, he was able to see the lives of Katar Hol and Chay Ara, coming to the conclusion he was the reincarnation of Katar Hol, destined to remember his past with the Obelisk.
