Hexblights

Three unique artifacts used to bring the Obsidian Hex to power among the Oni. The avatar of Rafna contrived to have the Forgefathers create the Crown of White Leaves while the Ash Dwarves created Obsidian Song and the Oni created the Shimmering Throne using the Apex Implements.
Together, the three Hexblights allow the wielder to absorb, store, and direct massive amounts of arcane power.
