Juno

Juno is a member of the First Civilization. She is portrayed in a holographic form to Desmond Miles throughout the end of AC Brotherhood. Juno appears four times after completing the path from the Collosuem in 2012. First, after passing through the first hidden entrance. Second, while Desmond is approaching the second hidden entrance. Third, after entering and flipping the switch inside the Santa Maria Aracoeli and lastly, inside the Vault beneath the Santa maria Aracoeli. Juno further expands Minerva's warning at the end of Assassin's Creed II. Her dialogue is also noticibly more hostile in tone towards humanity, than Minerva's. Once Desmond, Lucy, Shaun and Rebecca  reach the Apple's location in the vault, Juno forcefully takes control of Desmond, forcing him to unwillingly strike Lucy with his Hidden Blade.

Dialogue
After passing through the first hidden entrance

Juno: We commit this space to the epilogue of our ending. Let it be found by he who is deemed worthy. Let it guide him. Let it shape his path forward. Let it save the world we leave behind.

Desmond: Who are you?

After approaching the second hidden entrance

Juno : In the beginning we set our truths to parchment. To stone. To the memory of men. These proved impermanent things. Cleansed by fire. Cleansed by famine. Cleansed by flood. All the world is innocent once more. Innocent and ignorant.

After flipping the switch inside the Santa Maria Aracoeli

Juno: We did not build them to be wise. And now they are our final, faulted hope. You are they. You process the potential for understanding. But you broke our tools. Or turned them against one another. We have destroyed what we could. Sealed away what we could not. Most. Not all. And it does not take many to unwind the world. Here is a safe place. Eternal. To store objects. Words. Wisdom. But not life. Almost did we have the means. But time...time erodes us. We can distract him. We can see past him. Faint left when he strikes right. But his reach is so very long. His stamina unending. We cannot evade his grasp. Not forever.

After entering the vault beneath the Santa Maria Aracoeli

A hundred years I might speak and still you would not know us. You with five senses. Us with six. The one we kept from you. To be safe. Now, you can never know. Only try. Grasp. You can SEE. SMELL. TASTE. TOUCH. HEAR. Knowledge has been blocked away. After, when the world became undone, we tried to pass it through the blood. Tried to join you with us. You see the blue shimmer. You hear the words. But you do not know. WE SHOULD OF LEFT YOU AS YOU WERE. It is hard to stay contained. Knowing as we do. We wait for you Desmond. You will come here. You will activate us. You xxxxxxxxxxxxxxxxx (MISSING)

After activating the apple

Desmond: Whats happening? I cant move!

Juno: Your DNA communes with the apple. You have activated it.

Desmond: Let me go!

Juno: On the 72nd day before the moment of awakening. You, birthed from our loins and the loins of our enemies. The end and the beginning, who we adore and honour. The final journey commences. There is one who would accompany you through the gate. She lies not within our sight. The cross darkens the horizon.

Desmond: What are you doing?

Juno: The Path must be opened. You cannot escape your part in this. The scales shall be balanced.

Desmond: Stop. Please.

Juno: You know very little. We must guide you. Cease your struggle.

Desmond: No!

Juno: It is done. The way lies all before you. Only she remains to be found. Awaken the sixth. Go. ALONE!
