The Millennium Stone

The Millennium Stone is the stone where the Millennium Items rest.

History
=Creation== While the Millennium Items were being created by Aknadin by sacrificing 99 humans from Kul Elna, he put the blood, bone, and flesh in the Millennium Stone in order to forge them, with all slots for each of the Millennium Items the exact same shape and size as them.

Memory World
The Stone was in Kul Elna, and was used by Bakura to put the Items in the Stone in order to summon Zorc Necrophades. When he stole the Millennium Pendant and the Ring, he inserted them in the Stone. Later, during the Atem's, the Priests', and Bakura's fight, Mahado attempted to destroy by making a pillar fall on it, however, they failed when Bakura summonned Bone Snapper to protect it.

In the anime only, Bakura seemed to have merged with the tablet, then Zorc emerged, thus destroying the Stone in the process.
