You screw on your bulbous metal helmet, set up your gear, and head for the shallows...

The Dive Begins

You shuffle your weighted boots to the slanted shallow reef, just barely 2 meters down. You see a pair of vividly colourful fish shoot up from the unseeable depths ahead of you, the sudden bullets of green and purple breaking the surface, and curiously never drop back down from beyond the hazy liquid ceiling

You decide to not think too much of it, and continue to make your way deeper, spotting both bland and strange creatures alike along the way.
