Cephalon Cy Dialogue

Empyrean Celebration Stream promo image

Cephalon Cy is the entity responsible for operating the Tenno's Railjack ship and assisting them in Empyrean missions. He acts as mission control, due to his comprehensive understanding of the ship and space warfare in general.

Cephalon Cy is discovered in the Rising Tide quest, which sees the Tenno salvage and rebuild a Railjack ship. Cy aids them during the quest and is subsequently installed in the Railjack as its Ship Cephalon.

Boarding ship (Dry Dock)

Mission control

Cephalon Cy acts as mission control for the following game modes:

Cephalon Cy plays a large role in the Rising Tide quest, which introduces him and explores his past. He is also active in Operation: Scarlet Spear, coordinating Railjack attacks on the Murex. He has dialogue during the Call of the Tempestarii quest, as well as a handful of lines in the New War. Cephalon Cy is mentioned by crewmembers from Cephalon Suda and New Loka.
