 What message for humanity does the author wish to communicate, regarding the fate of the Ryzgas?
But its outward perils could not compare with the Ryzgas themselves, who slept within, ready to wake and conquer.... Now, if her father and his kinsmen overtook them, it would be death for Var, and for Neena living shame. While she waited he spun a dream, attaching it to the crags that loomed over the pass, and to the frozen ground underfoot.

And before very long, I'm sure, I would have performed some deed which Groz would recognize as a worthy exploit, and would thus have healed the feud between our families. I did not see the sleepers, nor will any man until they come again, but I met their sentries, the sentinel machines that guard them now as they have for two thousand years. There were tyrannies before the Ryzgas, there was lust for power, and atrocious cruelty; but such tyranny, power, and cruelty as theirs, had never been known. "Because of them we must build with dreams instead of iron, and our only fire is that of the Sun, and even now, two thousand years later, the Earth is still slowly recovering from the pangs and poison of that age. And we—we too are a remnant, the descendants of the few out of all humanity that survived when the Ryzgas' world went down in flame and thunder.
