The Orb of Goodbyes

From the publishers blurb: The Orb of Goodbyes is a magical item blessed with the power to extract and erase memories from a willing creature's mind. When a Waterdeep lieutenant retires from military service, she seeks the Orb to forget a dangerous memory. Those who help procure the Orb from an enchanted cave discover the secrets behind this magical artifact and unearth its hidden memories. The adventurers may then decide whether to deliver the Orb and help the veteran find peace, or use the item themselves to release burdens from their past.
