Story Mode[]
During Time To Split, Cortez arrives at HQ, where he meets with The General, and they talk about the Crystals and finding energy residues. After going up an elevator to the Time Machine room, the General introduces Cortez to Anya. Anya puts a Temporal Uplink on Cortez's arm and sends him to an island called Urnsay, where they believe the Time Crystals are located.
The place reappears in The Hooded Man, where Cortez must defend his past self and help him reach HQ safely.
