My plan you say? I guess I can share. It'd been a while since I have played Dresden Files so when my DM said he was doing a game it got me pumped. An not to long before he asked me I'd turned over Bloodborne and an idea came to mind immediately. So I ran with the idea of what if the main character, before he ascended to being a great one, presented Analise with the ring of betrothal and she accepted? My character concept is a young man who is adopted by two overbearing but loving parents, and he happens to be a descendant of these two people but does not know it. His dreams are filled with a red moon hanging low over gothic city where beast and all manners of dark creatures rule the streets. An the only thing stopping them from doing so are brave men and women garbed in black, using any and every means to combat the threat and shove them back. He is not clued in so of course this freaks him out and when he tells his parents they look at him like he's crazy, eventually he has another dream where he finds himself in an unfamiliar field (The Hunter's Dream) where a presence makes itself known to him. He can't describe what exactly it is he is seeing nor can he understand its alien utterings, but when it reaches out and embraces him tightly to it he is shocked. Forcing him to awaken to find a strange mark on his left palm and a greatsword that seems to emanate blue moonlight across his lap; then he accepts that something is really wrong with him.
Overall he's meant to be a Hunter in the present day, wanting to take up arms against the things that go bump in the night to protect humanity though he's 12 at the moment and has a long way to go. (Feet in the water level) My dm loved the idea and due to the prodding of another player whose mother was put in a drug induced coma and his character was conceived through a dark ritual by the sleeping Cthulu against there will. A rival faction stormed the sect, killed his mother and kidnapped him to trained him to be a terrorist in servitude of the great old one. They got raided by the white council and he used the distraction to slip away, living on the streets as a homeless child touch by madness. Keep in mind we did not collaborate in anyway, shape or form nor did we know of what each other is building and our dm, after reading more into it decided to add the Cthulu mythos to the mix.
