On the other side of the battlefield, far on the left of the no-longer-flying mountain, the Emperor was in a far dimmer environment.
The chaotic land the Source had created by unleashing a torrent of True Chaos did shine with dark light, but its glow was incomparable to what was happening on the right side of the battlefield. Khan was facing actual stars, and their radiance ended up claiming the Emperor's gaze.
Still, strangely enough, that distant light remained limited to its side of the battlefield, as if unable to invade the other perfect son's domain. The Emperor could only watch it from afar, as if gazing at a star from inside the safety of a planet's orbit.
The scene was truly magnificent, but the Emperor focused on features that had little to do with that spectacle of blinding lights. He sensed the incredible power on display and experienced bottomless gratitude, as well as profound shame.
