You've discovered a crystalline shard of power that resides within your spirit. This shard possesses various functions, all centered around the concept of Naming. Every existing entity, be it an object or a creature, has a true name. Initially, you can channel your willpower through the shard to study and discern the true name of what you're examining. As you delve deeper into understanding something and approach the realization of its true name, you gain conceptual power over it. However, dealing with sentient beings requires contesting, defeating, or subduing them before exercising full control.
This process may vary in difficulty, especially when it comes to your own true name. Accepting uncomfortable truths about yourself is often necessary to fully grasp your true name. Upon learning the foundational true name of something, the Key of Names crystallizes a version of it. You can then manifest and control these crystallized copies in the real world, as well as mantle other things with their true names.
Mantling involves overlaying a true name onto something to conceptually manifest the named thing's aspects. For instance, mantling the true name of a sword onto yourself might enable your punches to cut like a sword or transform yourself into the sword's form. Choosing which aspects are transferred during mantling is within your control.
The Key of Names bestows increasing spacetime control over crystallized true names. This allows you to summon or banish any true names you've crystallized at the foundational level, including your own, granting you temporal-spatial control over yourself. Sending named things back in time requires a high degree of mastery.
Additionally, the Key can be used to name places and things, but overwriting the true names of things demands mastery of their true names. Naming can alter various aspects of the object, with more significant conceptual changes requiring greater mastery. For example, changing a car's color is easier than transforming its engine. Naming a location requires realizing a few foundational true names and begins with a small area, expanding as mastery grows. Focusing on specific boundaries, such as a forest rather than a broad area, facilitates narrowing down a place's true name.
As mastery of the Key advances, you can realize the True Names of indirect concepts and gain control over them. However, initially, only tangible things that engage your senses can be studied and have their true names realized.
