After escaping the Coliseum, Snow happens upon the city of Yusnaan, where he helps its people, eventually becoming the patron of the city by popular acclaim. Snow has since been the ruler of Yusnaan for five centuries, although nowadays he spends his time locked up in his palace and his only active role is watching over the festivities. As a l'Cie, he is charged to protect the sole remaining fal'Cie that supports Nova Chrysalia through its final days. He harbors regret over having been unable to save Serah, wondering if he will see her again upon his death, and is becoming more Cie'th-like due to the influence of Chaos.When Lightning arrives in Yusnaan during the middle of a celebration, she fights her way into Snow's palace and confronts him in the ballroom, with Snow recognizing her as the Savior. As an outburst of Chaos and several Anubyses drive the partygoers away, Snow and Lightning destroy them before engaging each other in combat until Lightning overpowers him. Snow asks if she is going to kill him and "save his soul". She offers to help him but despite Snow's seeming willingness to die, he is angered by her answer.
Lumina appears, breaks Lightning's blade, and drops the large chandelier above the room. Snow halts its descend by freezing it, creating a structure reminiscent of the crystallized Cocoon, then spies something behind Lightning and comments that no one will stand in his way, even if it means fighting the Savior. Snow then flees with Lightning in pursuit and although she almost catches up with him, Lumina blocks her path with a monster, giving Snow the chance to disappear inside a Chaos Infusion inside the palace.
