question:  Var and Neena most likely belong to which group:
context: But its outward perils could not compare with the Ryzgas themselves, who slept within, ready to wake and conquer.... Var said, "The Watcher's cave should be three miles beyond this pass." Var sensed her fear, and the love that had conquered it. For the flame that had sprung between them at the Truce of New Grass, she had challenged the feud of their peoples and had left her home, to follow him. Now, if her father and his kinsmen overtook them, it would be death for Var, and for Neena living shame. Which of the two was worse was no longer a simple problem to Var, who had grown much older in the last days. Var eyed the ice-curtain closely to make sure that it was real, not dream-stuff; then he struck it boldly with his fist. Var saw with some surprise that all the walls were sheathed in ice—warm to the touch, bound fast against melting by the Watcher's will. Hot food and drink were before them almost at once. Warming to the old man now, Var sketched his and Neena's history briefly. The Watcher was broodingly silent; his eyes shifted to Neena, where she nestled by Var's side. Neena returned his gaze without flinching; then she looked sidelong at Var, and her lips curled with a proud and tender mockery. Now for the first time Var sensed the power in the old man's look, the power of four hundred years' wisdom. 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. They were great and evil as no other people has been, because they wanted the stars. "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.
