A vast expanse, often covered in snow, freezing for most of the year, and what little life there is often hides away from the weather where it can. How did Thorax survive that? A changeling, battered and weak, with the closest source of sapient love far, far away, is usually a dead changeling, and the tundra is very unforgiving.
Note: The prologue is filled with scientific jargon. It should be readable to most, though it might not be the easiest to go through, so I have a summary in the author's note at the bottom just in case. Later parts have narration more befitting Thorax.
