The 5 Prime Interactions govern and control all forms of organic and mechanical life in the 9 realms, from the binding of quarks and molecules to determining the orbits of planetary bodies and the forces of decay.
These 5 Interactions can be manipulated in near limitless ways bound only by the limitations of the users. Consistent across the 9 known worlds has been the ability to make use of these forces via expansion of higher brain function as in the case of Shaolin Monks of Earth and Dinn Warriors of Daemos or by technological means as with Os1 Central Intelligence.
A realm has neared complete evolution once it has mastered all 5 of the Prime Interactions. While many of the realms have done so via higher brain expansion, the Os1has reached near complete mastery via technological means.
