All 3 Titans + Kozilek Aura

All standing together, the titans moved down the canyon. The very light around them bent as a desert mirage might, and the rock they moved over cracked to dust. As they neared the edges of the canyon, great chunks or red rock broke off and desiccated to dust filtering down to the canyon floor.

The last titan slithered to the middle of the canyon, and even its sound did not adhere to the normal rules of nature. Instead of the crushing sound that should have been heard as it made the rocks flat, Nissa heard a high-pitched squeak and low, moaning roll as the sound in the canyon bent and reverberated in the titan’s dominion.
