You are an "Inscribed," a person with a word attached to your soul called an "Epithet." This allows you to develop various powers and abilities based on your Epithet.
Exactly what powers and abilities an Inscribed can potentially develop depends on two factors: the creativity of the Inscribed and the Epithet itself. Additionally, Epithets are somewhat unique, meaning that no two individuals will have exactly the same Epithet.
Someone with an Epithet of "Barrier" could potentially create/control barriers and block memories, while someone with an Epithet of "Dumb" could potentially reduce a person's intelligence, suppress sound, and weaken attacks, and someone with an Epithet of "Sundial" could potentially turn things forwards or backwards along any process, such as gravity, inertia, the cycle of the sun, and even a person's lifespan.
Epithets are powered by your stamina, so overuse of an Epithet can be exhausting.
(While Epithets are typically random, you get to choose yours.)
