Atlantis: The Lost Empire2001

King Kashekim Nedakh:
[about Kida] She has been chosen. Like her mother before her.

Milo:
What?

King Kashekim Nedakh:
In times of danger, the crystal would choose a host - one of royal blood - to protect itself and its people. It will accept no other.

Milo:
"Choose"? You mean, this thing is alive?

King Kashekim Nedakh:
In a way. The crystal thrives on the collective emotions of all who came before us. In return, it provides power. Longevity. Protection. As it grew, it developed a consciousness of its own. [coughs] In my arrogance, I sought to use it as a weapon of war. But its power proved too great to control. It overwhelmed us...and led to our destruction.

Milo:
So that's why you hid it beneath the city. To prevent history from repeating itself!

King Kashekim Nedakh:
And to prevent Kida from suffering the same fate as my beloved wife.

Milo:
What do you mean? What's going to happen to her?

King Kashekim Nedakh:
If she remains bonded to the crystal...she could be lost to it forever. The love of my daughter is all I have left. My burden would have become hers when the time was right...but now, it falls to you. [gives Milo his pendant]

Milo:
Me?

King Kashekim Nedakh:
Return the crystal. Save Atlantis. Save my daughter. [dies]
