Soul is the essence of everything. It begins as a spark, but through action and movement is stoked into a flame. Inanimate things lack the ability to nurture soul, so it remains as residual soul. Soul can be used to strengthen one’s body or manipulated to create a degree of outwards effects. One of such is the common evaluation of another’s soul by emitting a burst of soul. One’s soul is the marker of their ability, but it cannot speak to their nature. It’s also quite obvious if someone is checking another.
