Scientist, Advocate #2 and others in “Unfinished Business”

We still lack an adequate coolant. Liquid nitrogen would be the ideal substance.

Why are you not producing the substance?

We have tried, Advocate. This planet's atmosphere contains ample amounts of the nitrogen element. But converting the nitrogen into a useful form is beyond the scope of the materials we have on hand.

If you're incapable of manufacturing what we need, then you will acquire it in another way.

And quickly! Before permanent harm comes to those who are still alive!

I will not allow submersion into this pool to become our destiny as well!
