Spirits possess a "True Name" which is their actual identity.
If a True Name is known, it becomes possible to form contracts, dominate them, locate them, or seal their power. Therefore, spirits never reveal their True Name to others.
Because of this, spirits usually live using aliases or street names.
Revealing one's True Name signifies a level of trust equivalent to entrusting one's life.
