A Taste of Evil follows Rilira Fl'wr, a mild-mannered and soft-spoken but psychologically broken woman as she continues along a long-sought path of revenge while sharing her body with a psychotically violent Forgotten Elder Being. It is unusual for being a rare character study story and for its complex view on the nature of good and evil.
Chronologically, it follows Beneath the Mountain and is followed by a time skip ending in Tale of Tir and Nox, Part II.
