Amulet of Koji'maah

The Amulet of Koji'maah is an amulet that was created by Khona'mi through Mahka'la-Xen using Koji'maah's entire soul. The amulet itself has an unstable form, and is larger than the observable universe, as it has the ability to bend the laws of the universe to its will. Barely any of the amulet is accounted for, as it was shattered into fine pieces by an unknown force.

Graham's Shard
Graham's Shard is what is believed to be a shard of the Amulet of Koji'maah. First officially discovered by mathematician Ronald Graham, he claimed that holding it gave him sight of a "number that can destroy worlds," which he later named Graham's number. According to Graham, the shard was "about the length of a crayon, and about the circumference of a penny. It possesses a vibrant red color, similar to that of a ruby. When held, it felt not like a solid, or any other state of matter [he was] aware of - it was as if [he was] holding raw information in [his] bare hand."

Several theorists have claimed that Graham's shard never existed, as its whereabouts are currently unknown. According to Graham himself, the shard mysteriously disappeared, despite extensive attempts to keep it safe.
