Rod of Seven Parts

Info

Eons ago, a war between the primordials and the gods scarred the planes of existence. A demon lord named Miska the Wolf-Spider eventually pushed the primordials’ enemies to the brink of annihilation.
Desperate to save themselves and their allies, powerful elemental beings called the Wind Dukes of Aaqa rose against Miska. Committed to the concept of law, the Wind Dukes descended from a people called the vaati, who once ruled many worlds. Seven Wind Dukes wove their power into an artifact called the Rod of Law. The dukes used the rod to imprison Miska on the plane of Pandemonium. As a result, the rod shattered into seven parts that were scattered throughout the multiverse. The rod thus became known as the Rod of Seven Parts.
