Story
Exploring the Corridors of Time
You've saved Saint-14, but you've left the Corridors of Time largely unexplored. See what you can find.
Overview
Exploring the Corridors of Time is a limited-time puzzle activity on Mercury from Season of Dawn (14-28 January 2020). After you rescued Saint-14 in the story missions, Osiris offered this quest, and activating the Sundial let players re-enter the Corridors of Time.
How it works
Rooms are filled with Vex and have six doorways marked with glyphs (Plus, Snake, Clover, Hex, Diamond...). Picking the right door sequence leads to the Timelost Vault. The puzzle had three layers: hourly-changing seven-glyph Obelisk codes, an 11-glyph emblem code and a 30-glyph final code with up to 5,040 nexus variants.
Rewards
Lore entries from the book The Pigeon and the Phoenix, the Savior of the Past emblem and the Memento quest leading to the exotic fusion rifle Bastion.
Notes
