"But in this world nothing can be said to be certain, except death and taxes."
"For Man to be able to gain something, something of equal value must be sacrificed in return. This is the first law of Equivalent Exchange."
Basic Story Premise: You want something. It is that one thing your soul yearns for the most. You have got to have it. It must happen. No matter what, no matter how it happens, it has got to. The ends justify all means at this point, and you'd literally do anything for your wish to become a reality. Luckily for you, you've met someone that might be of service to you. Meet Astaroth, a sharp-looking young man that is willing to lend you a hand. "With our powers combined, even the most impossible of miracles are within your grasp!" he tells you, smiling warmly. He looks nice enough. Maybe this is just the help you need? He continues, "Listen, maybe we can reach an agreement? I, Astaroth, can grant you almost any wish imaginable. The laws of this universe mean nothing to me. The one thing you yearn for the most can be yours with two words: 'I accept.' However, I am not one to just hand out favors, honestly, so I'm going to require you to return something to me in exchange. Actually, I have just the thing to start off with. There's a group of people like you whom I work for. We're called the MIST organization, and we're always in need of new blood. What say you? You scratch my back, I scratch yours."
Desperate for the thing you desire, you eventually agree to the terms of the contract (even if you didn't read the fine-print too closely) and sign your name. Suddenly, Astaroth pulls something out of your chest and plops it into his mouth. Overcome with a strange weariness, you pass out. When you wake up, you're in a different place. Astaroth did in fact hold up his end of the bargain; your wish came true completely. However, it's your turn to repay the debt you now owe...
Welcome to MIST. We are an organization that deal with the Mysterious, Intradimensional, Supernatural, and Terminate any of those that cause a threat to mankind. Congratulations, you are now a part-time monster-slayer. Alongside the wish you requested, Astaroth has also granted you certain powers to aid you in this endeavor. How else could a mere human stand up against a swarm of ghosts or whatnot? You can be called to serve at any moment, even at the most inconvenient of times, and must follow through promptly. Disobeying the terms of your contract means certain death. There are no vacation days, so don't even ask.
(I'm going to add more should this general idea get any sort of positive feedback. Also, it's very late as I write this, and an incoherent mind won't be able to convey a plot that easily. As of right now, do I have anyone interested?)
