Lelani Caladon
The wife of Landor Caladon, she was murdered by him in a fit of jealous rage.
Lelani suffered in ghostly torment for decades, reliving her last moments, in which she lost her unborn child and her life. This lasted until the undead summoned by her grief and the powerful dark magick surrounding her deathbed kidnapped Rachel Weaver. After a series of events, culminating in Perrin Forester putting his foot in his mouth up to his knee, Lelani possessed the pregnant Rachel.
The Companions of the Rising Sun elected not to exorcise her, believing that the most efficient and kind way to send her on to the afterlife was to simply let her ride along for the birth of the child in Rachel's womb.
Lelani proved to be an asset to Rachel's safety, at one point manifesting and killing or destroying several attackers who attempted to either gain access to the Companion's residence, or possibly even kidnap Rachel and her unborn child (it is unclear). In so doing, she also set fire to the building, and subsequently guided Rachel to sanctuary within a monastery belonging to the Order of The Fist of Reverence.
Lelani apparently went to her eternal rest with the birth of Landor Forester, as she is no longer with Rachel or the child.
