Nothing lasts forever, but in the multiverse, the realm of Forge perhaps comes closest. The core of the realm is long lost, and its people live on a series of nested spheres built up over the generations more quickly than the realm’s earthquakes and acid tsunamis can destroy them.
Miyamune is Forge's realmlord. Indifferent to worship, he crafts the multiverse's most exquisite weapons on a timeline that makes factories and flowers seem equally fleeting. When Miyamune deems a blade perfect, he then crafts a warrior to wield it, before sending both across the cosmos to test his creations on the battlefields of other realms.
