You decide that you have to continue on, there's too much that could
lie ahead to turn around and give up.
You swim farther and farther into the cave. The water is becoming
increasingly blue, and warmer and lower.
Soon you are no longer swimming but crawling in a pool of water.
Or so you think...
As you crawl, the water seems to become lower. Then you find out, the
hard way, that it drops steeply into a emerald green water.
The water is different than the other water, in this you sink rapidly
dispite all the swimming that you do.
You start to loose your vision, you feel yourself drowning
when...
As you swin farther into the cave, it becomes lighter. The waters
become a clearer blue, and the water becomes lower, there are air
pockets that allow you to breathe.
