As he gradually entered the crack, garen's vision was pitch black.
The light seemed to be completely blocked by the rugged and winding cracks, unable to project down. In the dark and deep environment, only the sound of the cold wind whistling could be heard, which was creepy.
Garen had night vision.
However, night vision did not mean that one would not be affected by the darkness.
The true Dragon's Night vision was due to the fine structure of the eye crystals, which could restrain the weak light in the surrounding environment to the greatest extent, and maintain one's own vision in a dark environment.
When the light was extremely weak, darksight was useless. It was not a supernatural or spell-like ability. In fact, it was just an ability possessed by the living body itself. Many nocturnal creatures had darksight, but it was different in strength.
Thus, during the descent, garen cast the illumination spell that he had learned a long time ago.
