The main purpose of this guild is to take topics of light and bring them into the darkness. In other words, horrorize them.

The basic gist of how to do that is simple: Take a topic that does not incorporate any (Or at least very minor) elements of horror and introduce some doom and gloom to it via a "what if?" proposal.

Sounds complicated? It really isn't. But my wording might make you think otherwise. So, let me just give you an example instead.

If I wanted to discuss what I (and others) would think a Super Mario game would be like if the Mushroom Kingdom was overrun by zombies, I would simply create a topic along the lines of "What if the Mushroom Kingdom was overrun by zombies?" (Though, the title of the topic doesn't have to be in the form of a "what if" question. It's just preferred.)

Easy peasy, no?

In saying that, now that you (hopefully) got the basics of horrorizing something down, I'd recommend unleashing your demented perspective on the world AS SOON AS POSSIBLE! Mwuhahahahaha!
