Harmonizers are beings of an incredibly ancient bloodline with the unique ability to interact with machinery specifically coded to their genetics. These Harmonizers can appear in any number of species that the bloodline was given to, but it is incredibly rare to encounter.

Guardians are constructs that were created by an incredibly ancient race. These constructs were often towering entities capable of unleashing unimaginable devastation, but although they can take many forms, there are typically a few traits that bind them together. Almost all of the Guardians appear to be covered in some kind of stone facade, and they are all almost always modeled after animals. Why these entities were designed in such a way has long since been forgotten, even by Estria, but their current function is clear. Their purpose is to protect the core of the planet, and they will violently put down any intrusions no matter who it is that comes knocking.

Hailing from foreign soil, the Steel Legion is an advanced army backed by cutting edge advancements. Whereas most of the world still fights with bows and swords, the Steel Legion has jumped forward by leaps and bounds to create weapons of incredible power. Their ranks included armored suits equipped with mortars, powerful tanks that can level towns in single shots, and colossal battleships that sail through the clouds. As of right now, their motivation is unknown, but it is clear that they have some interest in the Guardians and the technology that powers them.
