History of Mouse

Overview

Mouse is a Triumph in Destiny 2 tied to the lore book Revelation, added in Shadowkeep. The book holds records from the doomed K1 expedition and its contact with the Anomaly inside the Moon.

The entry behind it is a personal message from Dr. Janet Green to her daughter, "Mouse", recorded from the Moon, where she has been sent on a secret assignment to help decode a signal that may come from another Traveler. She apologizes for leaving without a goodbye hug and says she will record a message every day. A later entry, "Boxing Day", shows her growing distressed as Clovis Bray prepares to box up the transceiver and move it to a new facility.
