Entity: Soul Warden

Source Book of the Dead pg. 26

You consider yourself an honorary psychopomp—a shepherd of spirits who ensures the cycle of souls progresses unimpeded. Although you're unable to safeguard the cycle of souls in its entirety, you strive to ensure each soul's time on the Material Plane proceeds without incident. You work to free souls from imprisonment, prevent necromancers from animating the dead, and destroy undead so their souls rejoin the cycle.

While most who hunt undead do so out of fear, vengeance, or a desire to protect the lives of others, you take a more measured and far less emotional approach; you destroy undead so their souls can continue their journey along the River of Souls, thus ensuring the continuation of existence. You understand that without the cycle of souls, the life cycle of the planes is disrupted, and all of existence could be consumed by the Maelstrom.

Nearly all soul wardens worship Pharasma or one of the psychopomp ushers, especially Barzahk the Passage, a psychopomp usher who routinely shirks their duties and needs help from mortal soul wardens. Soul wardens also often join organizations that regularly combat undead, including the Voices of the Spire and Ustalav's Ivory Reapers.
