First, there was nothing.
Just text, on a forum wall.
But that was boring,
So some huge asshole was all like:
">Begin SWATCHQUEST".
And that's exactly what happened.
This is the prophecy foretold by that same huge asshole from exactly 10 minutes ago when they opened up FireAlpaca and turned of anti-aliasing,
A prophecy that predicted what was to come in the next like. 30 seconds from now.
>Begin SWATCHQUEST.

Welcome to SWATCHQUEST! The name is pretty misleading, you aren't questing to anywhere.
But you could.
Let's examine your OVERLAY.
First up is the PAINT button. In here is your PAINT SWATCH and handy BRUSH. You can draw whatever you want.
Next are your TOOLS. You've got lots of them. Want something to be sentient and feeling? Use the SENTIZER. Want something to carry out a specific task? Forever? Use the PROGRAMIZER. And, so on and so fourth.
Finally, the NODES button. This, of course, lets you see all your NODES. These add prefixes to your TOOLS, making them carry out a different action. Like, for example, a DE-SENTIZER. Or an EX-PROGRAMIZER.
If you want more in depth looks at any of these, just ask!
Of course, if you don't feel like programming, say, a door to lead you on an epic quest, you can always just leave it up to fate and have the Huge Asshole from the prophecy decide for you.
This is not another trilogy, it's just another story.
