It is the nature of all sentient beings to pursue an end with the entirety of their being. Power. Immortality. Status. Such incentives will always drive individuals to even the greatest extremes to acquire what they desire above all else.
Even the people who populate the harsh tundra of Freljord will come to see the Glorious Evolution as the salvation that they will need in their greatest desperation.
If you truly cared about your people, you would be wise enough to know that my promises of evolution could only benefit you all and prevent the end of your entire culture.
Keep dreaming, maybe it'll REALLY happen.
