Esher's Speech near the Thermal Engines
"I was not so sure of you. And yet, you have done well. But...do not be proud. You think you understand what you see...you may be wrong.
For example...this appears to be ice, but there is more. Like the prisoners, there is life here that seeks heat. Unseen life...in the water.
There is no longer heat in this place. But you can make them bring it." - Esher
