Time Stone (Earth-Prime)

"What is this? It's a gift. Father to father. And I think you're gonna need that some day."

- Joe West and Damien Darhk

The Time Stone is a mystical stone that is capable of Time Travel.

Secret of All Life
In 2021, John Constantine was killed in Bishop's attempt to eliminate the Fountain of Imperium. Constantine then traded his soul with a demon, with the Fountain, now brought back by to life, evicting Constantine from itself. Later, Constantine revealed himself to Zari Tarazi, giving the key to his pocket dimension and leaving 1925 with his Time Stone.

Reverse Flashpoint
When Eobard Thawne created the Reverse Flashpoint, Barry Allen was altered to be the Reverse-Flash and was trapped in 2031 with depleting speed. Hoping to reset the timeline, Allen turned to Damien Darhk and retrieved the Particle Eradication Distributor from Team Flash. Combining Darhk's Time Stone and the distributor, Allen ran back in time and eradicated all Time Aberrations from the temporal plane, with Darhk being drawn with him back to 2021 despite his death a year prior.

After the defeat of Thawne and Despero, Darhk gave the Time Stone to Joe West and hoped that it would assist him in the future. As soon as the stone was given to West, Darhk was absorbed into the Time Stone and given a final chance to talk to his daughter, Nora. Soon, Nora was released from the Time Stone and appeared next to Team Flash, with West explaining the situation to the confused Nora.

Death of Iris West-Allen
Soon after Iris West-Allen suffered from a "Temporal Illness" caused by the Negative Still Force, with Allen killing her in an accident, her existence was preserved in the Time Stone. Jay Garrick and Joan Williams of 2049 traveled back to 2022 and found the Time Stone glowing in the West House. Meanwhile inside the Time Stone, West-Allen conversed with Darhk, with the latter successfully convincing the former to escape the Time Stone.
