Threnody

A threnody is a series of words used to banish spirits to the outer darkness. It is a kind of spell.

Description
Banishment requires knowledge of the spirit's name, but chanting the rest of the threnody will still weaken and distract a spirit to the point that they may not be able to defend their "host" voyant. To conduct a threnody, a clairvoyant must adhere to the following: "[Name of spirit], be gone into the æther. All is settled. All debts are paid. You need not dwell among the living now. Good-bye." Paige Mahoney speaks the threnody for Sebastian Pearce's spirit before escaping Sheol I.
