The Skall Syndicate, originally the United Legion, is a commonwealth empire mainly located on Skull Island and the Machard Islands. It was comprised by the remnants of the Raesta Collective and the Legions of Olop Ocram after the massive war on the Armada.

The syndicate originally was a militaristic powerhouse, controlling the majority of the Spiral for over a century, before various uprisings and loss of soldier threshold minimized the empire. The Skall now contract pirates.
