Indefinite
The darkness felt indefinite. Ryu's consciousness was blurry and he couldn't seem to see anything but a fuzzy light at the end of a tunnel that must have been countless kilometers deep. His steps felt as slow as a mortals, and no matter how hard he ran, he felt like he was moving through water. He couldn't sense his qi, his Spiritual Foundations, he couldn't even sense his Spiritual Sea, the one among them that should have been the absolute easiest to do so.
It was a helpless feeling, almost like a child floating within their mother's womb, but this feeling held no sort of comfort. There wasn't the calming whisper of a mother's voice, nor was there the warmth of a mother's nurturing, there was nothing but an endless void, a depth of coldness that was almost unfathomable to the masses.
