In life, Zaress was a crusading agent of Lathander. She met Evelyn as a spirit, waiting to be devoured by the Soulmonger. [1]
Evelyn met Zaress again in the afterlife, where Zaress became a mentor figure to her, and attempted to impart the wisdom that is is also Lathander's will that she be happy, and consider what she wants as a person, rather than being strictly a tool of her god.[2]
