As you know BlackJack will be returning to Deadwood after the restart. However, he will not be there at the start. Black will come in later, likely when the first wagon train arrives. But what to do? Fortunately, there is another character which will be in Deadwood. His name is Ezra Macarthur and he is a miner/prospector. Currently Ezra is a half breed (white/Indian) miner. In his reincarnation at the restart Ezra will be a prospector. I have not worked out his complete backstory yet. Right now I am thinking he will be a man of indeterminate age, worked in the Comstock strike. I am fairly sure he will be, for the most part, a law abiding citizen. Real life inspiration for Ezra is drawn from the miners/prospectors who dreamed, worked, stole, even murdered for the chance to strike it rich.
BlackJack's backstory for the restart is not set in stone as of yet either. Though, I think he will be one who jumps back and forth on the fence of law and order, though likely being on the wrong side of the fence more often than not. I am currently doing some research on various lawmen and criminals on whom to base the new Black. Maybe someone like Soapy Smith? or Burton Alvord, who was a lawman turned outlaw? Perhaps an amalgamation of both or more indiduals?
I have to say the planning for the restart has proven to be a blast. If the planning is so much fun, just imagine how great the actual rp will be. If any who read this have not been to Deadwood, then I encourage you to go to Second Life, create an account if you do not have one (you can get one free). Then do a search for Deadwood and come visit us. You will find some of the nicest people in SL there.
