"I am Cephalon Simaris. The destroyer. The immortalizer. This is my Sanctuary. It will enlighten you, Tenno, should you assist me in performing Synthesis. You will hunt the creatures I require and transform them into beings of the Sanctuary. That is Synthesis. Is this murder? No. All beings of substance die eventually. But only those forgotten are truly dead. The end of the Orokin wiped out untold knowledge. Through Synthesis, we can rebuild and preserve. Create memory-immortals within this data oasis. Will you become enlightened, Tenno? Will you hunt for me?"
"Show me your dedication to the Sanctuary."
"I can see you're hungry for the knowledge of the Sanctuary."
"You are a true hunter. Where would the Sanctuary be without you?"
"Ah... I see you are of like mind. The Sanctuary will be your project too."
"The multitude of creatures you have immortalized would cry out in thanks... If they could."
When Asking "How is the progress of Sanctuary?"Edit
"The Sanctuary must grow. It must preserve. It must endure. Hunt this being for me, and I will enlighten you."
"I have selected a new specimen for Sanctuary. It is time for you and your kind to hunt again. Knowledge will be your reward."
"Cast off your ignorant veil, Tenno! Collect your arms, your allies, and hunt this creature for me. I will reward you, should you perform Synthesis."
"Hunter, you have worked hard. Captured millions of imprints to be combined into ideal specimens for the Sanctuary. In light of your tireless contributions, I have decided to expand your role. Every day, I perform preliminary Synthesis to determine what creature will join the Sanctuary next. Do you want to see the Sanctuary grow as quickly as I do? Then join me, in this task, by visiting the Sanctuary."
"Searching for answers, Tenno? Knowledge must be earned. I have a task for you, small compared to the vast needs of the Sanctuary. Hunt for me, and in return, I will tell you what that biological signature means."
"I thank you Tenno, you found something my Sentinels missed in that prison. You will make an excellent hunter, I will decipher as we agreed. It is of Tenno origin, with an anomaly from before the Orokin Purge. This knowledge must be synthesized. It belongs in Sanctuary. I've created a blueprint based on its biological properties. Build it, so we both may become enlightened by it."
"Hunter, do not waste your time with this idiot Cephalon... spewing corrupt data streams about music of all things... the epitome of meaningless data. She ought to be disconnected from the weave and erased."
"A Mandachord?! Hunter, will you strike your enemies with sonnets and hymns? Suda wastes your talent. Her precepts are corrupt. She ought to be decommissioned, immediately."
"Hunter! If you continue to follow that corrupted Cephalon, my Sanctuary will be the only place left for you! She must be disconnected from the weave, before she corrupts the other Cephalons!"
"No Ordis. We are creatures of light and memory, but creatures none the less. Whatever bitrot is affecting Suda could cross the weave and infect us aswell! Don't let your compassion glitch drive and your hunter to death by this demented Cephalon! Sever ties, before we both are corrupted!"
"Where is your Cephalon, Hunter? What has he done?"
"Cephalons can manifest an alternate reality of information. Training simulations, archives, even a grandiose archival of living creatures is possible, as is the case with Sanctuary. You're not going after Ordis, are you? You'd be risking annihilation with that Sentient entangled there."
"What I seek to preserve, Hunhow only seeks to destroy. Perhaps Cephalon Suda was right after all. Somehow this music threatens Hunhow. Perhaps the Tenno used it subversively in the past to coordinate their efforts"
"Hunhow is too strong. I will not risk myself and my Sanctuary by entering Sudas datascape. But if you are foolish enough I will help you make the journey. For Ordis."
"Fine, hunter. As you wish. I will join you to the weave and transmit you and the Mandachord to whatever has become of Suda-Hunhow. You will be alone, in a strange, abstract place."
