Description
At the top of the mountain, where the creator of the robots lives, stands a tree with fruit that contains special electrochemical properties. This tree and its fruit are used by the creator to build robots, and is the secret to what gives them life.
Symbolism
The tree bears symbolic similarity to the tree of life, and helps reinforce the idea of the creator as a sort of stand in for God. However, it does not play a major role in the overall story.
