He had to keep going. There was no other way out, yet he was drawn deeper and deeper into the abyss, like a moth to  a flame - helpless.

It was down there. Somewhere in the cold blue, between the jagged rocks. Waiting for him. He needed to find it, reach it, face it.

The tank was almost empty. His breaths were starting to become labored, pulling out whatever oxygen was left in the polished steel container. His hands were pruning, feet numb, legs cramping from exhaustion. He wasn't sure if he would make it, but as long as there was air in the tank and the flashlight kept showing him the way, he would continue.

It's when the light died that the true trouble would begin.
