The Chalice

The Chalice was a virtual representation of one of Altaïr Ibn-La'Ahad's genetic memories, relived by Desmond Miles in 2012 through the Animus.

Description
Having rescued Adha from the Templars, Altaïr planned to escape with her through the sewers.

Dialogue
Altaïr killed the guards and walked towards a pressure plate. Adha dropped a metal crate to Altaïr's level, allowing him to move it to the pressure plate and advance. Emerging out of the tunnels, Adha appeared above Altaïr, blocked by a pillar. Altaïr threw a bomb at the pillar, causing it to crumble and allowing Adha to cross. Cooperating with Adha, Altaïr traversed the sewers, eventually coming to an obstacle for Adha. Altaïr stepped on three pressure plates, stopping the water from flowing out of the tunnels and allowing Adha to cross safely. With more cooperation, Altaïr and Adha managed to reunite at the sewer's end.
 * Adha: I see you have good plans... You ended up there and I here.
 * Altaïr: Actually, it didn't go exactly as planned...
 * Adha: What now?
 * Altaïr: Advance and we'll see. We must get to the end of this sewer.
 * Adha: Careful, there are guards in your path!
 * Altaïr: I need a weight to open this door...
 * Adha: I think I can help you with that, Altaïr.
 * Adha: I'll try to find my way through these tunnels, Altaïr.
 * Adha: I'm here, Altaïr! But I can't go any further... Can you help?
 * Adha: Altaïr! Help me with these tunnels!
 * Altaïr: The exit... Let's hurry!
 * Adha: Altaïr, wait. There is something I have to tell you. The Templars were trying to buy off someone from your Order. The last I heard about this, they succeeded.
 * Altaïr: Who?
 * Adha: A man named Harash, I think.
 * Altaïr: It cannot be. Harash is the Keeper of the whole Order. Only Al-Mualim is above him... Is there any proof of this? Otherwise...
 * Adha: No. But as long as he's alive, I cannot follow you. They'll get to me. I'll be taken and kept hidden again, until someone pays the price.
 * Altaïr: I cannot accuse him without proof.
 * Adha: You have to kill him. You have to stop the Temlars, Altaïr.
 * Altaïr: I cannot go back.
 * Adha: What will you do?
 * Altaïr: I'll head on to Tyre. There's a boat there; we can escape.
 * Adha: Kill him, Altaïr, and then come with me. We'll hide, we'll go as far as possible.
 * Altaïr: Alright. Wait for me.
 * Adha: Take this sword, Altaïr, as a gift. And please be careful!

Outcome
Troubled by Adha's words, Altaïr set off for Tyre.
