It is first unearthed in 1945 and recovered by the SSR from HYDRA making it the first 0-8-4 identified object by S.H.I.E.L.D. By physical touch "The Obelisk" can kill people and affects human skin by visibly turning the section that touched it black. It is a silvery color in the form of an abstract shape.
When opened, it is revealed it is a Terrigen Bomb, and when put in a Terrigen chamber, released the Mist which gives Inhumans their powers.

Later, Zabo tells Coulson that the Diviner is the key to finding an ancient temple, Coulson asked if it was like Tesseract but Zabo not know it was that. Whitehall forces Skye to touch the Diviner when she touches the Diviner, this begins to shine. While Raina and Skye talk, suddenly the Diviner started to float and moved to a pedestal.
