Chernabog's Thirteen Seekers of Darkness are an ancient group of villains who fought during the Clash of the Keyblade Wars. By clashing with the Keyblades of another 13, the 13 Seekers of Light, they separated the X-Blade, the Keyblade that unlocks Kingdom Hearts, into 13 pieces currently the result of a merge between the Seeker of Light's Keyblade and the Seeker of Darkness's Keyblade. These blades are currently hidden across the UUniverses by The High Council for safe-keeping.
