Soul Sigil

The Soul Sigil (also known as the Spiritual Matrix) is a metaphysical representation of a person's soul and their capacity for magic. It dictates their Mana Capacity, their Loop-Sanity, and their Soul Integrity.

Unlike the physical body, the Soul Sigil does not reset at the end of the time loop. This is why mages retain their spell knowledge, memories, and traumatizing soul damage even after waking up back on Day 1. Alterations to the Sigil—whether beneficial like a new Specialization or detrimental like Soul Damage—are permanent across all iterations.
