From the introduction: Grief is a part of being alive. As there is joy, there must be sorrow. It is perhaps the most natural response to loss, particularly the loss of a life. Grief can be a cathartic form of healing. It can also consume a person if they fall too deeply into it. Therefore the Grief domain attracts gods who represent its different aspects. Gods of life, nature and endurance -- including Ilmater, Hestia, Diancecht, and Boldrei -- have access to this domain. This is also holds a place for gods of death and loss. Kelemvor, Nephthys, Arawn, Hades, and Shar know grief and the power it can have.
