"... you do not know how you got here. The last thing you remember is going out to eat at a fancy restaurant. Perhaps you were drugged. Perhaps you had a bad case of food poisoning and wandered off, feverish, into the outskirts of town. Whatever the case may be, you are here now. Wherever here is. And you want to leave." - Author's description
