Who is Mr. Johnson?
Lets just say that nothing happens in the shadows without Mr. Johnson. He's the guy who needs the job don - on the quiet, so that the folks he answers to can keep their hands clean. He's the bridge beween the "respectable" workd of corprate execuatives, goverment higherups and such as the shadowy streets that runners call home. He does the hiring and pays the cred. Deal straight with him and nine times out of ten, he'l deal with you straight. (As for the tenth, hell nobody ever said that running the shadows was fraggin' easy.)
Whatever you need to know about a particular job, the Johnson can you - the layout of the lab where the top-flight researcher you're suppose to kidnap spends all of her time, or how often security guards patrol the facility you've been hired to trash. He also knows people who can get you what you need to do the job right, from trasport to good fake I.D.s to passcodes for a rival corp's matrix system. After years of working with fixers and other citizens of the shadows, Mr. Johnson's made a lot of contacts. Impress him with a job well done and you might be able to tap into the network. Mess things up or double cross him, and Mr. Johnson is likely to make you dissapear, forever.
