As Lyra exits Hades’s Lock, the archway seals behind her. She negotiates with the Titans, agreeing to try to unseal the Seven Locks if they help prepare her.

Mnemosyne leads the group through tunnels lit by sconces and the Titans’ own glows. They pass a cell where Ocnus is condemned to weave an eternally eaten rope. Iapetus warns Lyra to avoid doors marked with an X, which can kill and reset time. Mnemosyne’s weary tone makes Lyra contemplate how many times she might have already died in previous timelines.

At the map room door, Lyra states that only Rhea, Phoebe, Mnemosyne, and Koios may join the planning session. Cronos protests, blaming Iapetus for throwing Lyra into the second Lock. When Lyra accuses Cronos of castrating and decapitating his father, Rhea intervenes, explaining that revealing the true story would reset time by 150 years. However, Cronos vehemently denies that he ate his children. As Lyra enters the map room, she walks directly into a shard of broken time.
