"...To safeguard the future of my world." Maybe it's simply a trick of the the light, or because of how they lingered beneath the shadow of the Black Lion, but for an instant, it's as though his eyes faintly glow crimson.

He shakes his head, adding, "It differs, but their blessing is always temporary. One way or another, they who wield the light of the Lucii have to face the fact that they will burn. One way or another. Even me."
