Omenseers

"In exchange for protein, shelter, and protection from other Hominins, I will help you navigate and act as a guardian for your journey. I will read the omens and guide you to safety, whatever your destination. In the current era, I can help you ward off the poor lost souls so you can navigate the sunlit seas."

- Arbitrator I, to Ulyana Korabiskaya

Omenseers are a group of humanoid biomechanical Leviathans that exist as a primarily nomadic society.

Overview
Omenseers are often unnaturally pale with white hair, with many choosing to dye streaks for the purpose of individuality. Omenseers require protein in the form of the flesh of hominins to make use of their own version of psionics called omenseeing. They are capable of surviving off of the meat of other animals or human blood, but become weaker and less capable of making use of their abilities.

Omenseers are Leviathans that have been either forcibly or through their own will 'uplifted' into their current form. Arbitrator II's process for performing this binds their auras to her, allowing her to command their bodies and communicate with them over vast distances. It is capable to escape this bond through a process available to Enforcer I.

Omenseers are capable of consuming fruit from a Garden of Marrow to gain much greater control over their bodies, allowing them to create weapons, modify or heal their bodies rapidly, and create leviforms from their flesh suited to their caste or need.

Castes
Arbitrator, a role with capability for leadership and a wide array of psionic and omenseeing abilities. Arbitrator I and Arbitrator II are the only two examples of this caste. Arbitrator I abstaining from consuming the flesh of hominins and Arbitrator II's role as the Apostle of Aether make it difficult to judge the full capabilities of this role. Both Arbitrators are actively aware of the STEM built into their bodies.

Enforcer, a handpicked caste of the most powerful servants of Arbitrator II, each carrying a unique title and name. They possess incredible control over their omensight and are trusted to lead and command forces themselves. Enforcer I possesses the ability to break the control Arbitrator II has over those she uplifts.

Sentinel, a Third Sphere caste purpose built for strength and loyalty.
