Hundred-Handed One

A spectrum of Giants claims territory across Theros, drawing Strength from aspects of the world itself—from ancient stone and roiling flames to the depths of the seas and skies. Unlike many creatures of legend, most Giants owe their existence not to Nyx and the dreams of mortals, but to natural forces in the land. As a result, Theran Giants are typically infused with the elements they embody, which might manifest as flaming beards, frozen skin, hair crackling with lightning, or other primal incarnations. Beyond these primal Giants, though, other Giants fill the tales of Theros.
Extra pairs of arms magically orbit the bodies of the titanic, nearly forgotten artisans known as hundred-handed ones. These Giants often dwell in remote mountains and Seaside cliffs, where they carve their memories into the ancient stone, covering their territories with intricate reliefs and massive Statues of bygone ages. Some linger near ancient temples and palaces, ruins they once raised to the gods or archons of old.

Artisans of the Archons.

Legend has it that the hundred-handed ones were once a tribe of giant artisans, prized by archon tyrants for their ability as stone cutters and smiths. The archons became greedy for more splendid monuments to their greatness. Some believed the grandest testaments to their glory were being denied them by their servants' unremarkable forms. So the archons performed dark Rituals, robbing the power of ancient, slumbering Giants and using it to transform their servants. This primal energy granted the archons' agents numerous limbs—the better to raise the archons' monuments and fortresses.
Yet many of the transformed Giants refused to be part of the archons' war machine. Seeking to Escape their masters, they fled into The Wilderness. The furious archons' magic pursued them, cursing them with an endless will to create, but no one to create for and none who would ever appreciate or use the art and architecture they created.
