Weatherman's idea was to establish a private company that offered its services to law enforcement agencies on an as-needed basis. Naming this organization the Trident Group, Weatherman, through his massive network of FBI and local law-enforcement contacts, advertised his company as a cutting edge criminal investigation consulting firm that drew on non-traditional approaches to solving crimes. His employees, most of whom with backgrounds in science and law enforcement, were hired out by law enforcement agents who had reached a dead end in their investigation. Not all of his employees knew about Delta Green or the Mythos, but for those that did, they were able to approach many previously unsolved cases with a unique "insight," and provide the needed information to bring the case to a close. Because of their successes, the Trident Group quickly established itself as an excellent resource for baffled law enforcement agencies around the country.

Weatherman still runs the show from his head office at the NW corner of a 3-story building in downtown Seattle, though as he continues to age he is devoting more and more time to ensuring his company's success after his death.

His office has an administrative staff of 18 people who are totally unaware of the company's true nature. Locked in his office behind a Salvador Dali painting on his office wall, Weatherman has a portfolio of a few dozen names of active advisors that he calls in when he feels their area of expertise suits the cases that law enforcement agencies throw at him. About a 20 of these names are marked with a green triangle, indicating their station as official Delta Green friendlies. These individuals have a wide range of skills and knowledge that help them beat unbeatable cases, much to the surprise of many stubborn law enforcement agents who don't appreciate the "help" of outside civilians. As for the rest of his team, their skills are entirely mundane in nature and their success rate is significantly lower.

Weatherman was a long-time Delta Green agent in Cell P and is on very good terms with Cell A, who trust him with the sort of information regarding Delta Green personnel that they might otherwise keep close to their chest. Since retiring from Delta Green, his former Cell P was reorganized, so Weatherman has very little, if any at all, information about Delta Green's current cell structure. Cell A will occasionally inform Weatherman of a new Friendly with relevant skills, who will update his portfolio book accordingly.

His top advisors bring a number of valuable skills to the table. Several of them are legitimate psychics, with such gifts as retro-cognition and remote viewing. Others, such as a women from Houston who works part-time as a palm reader, has knowledge of the occult and Mythos magic. Others are merely men and women who have seen some really fucked up shit and thus can approach unsolved crimes with a more open, if slightly disturbed, mind.

The Trident Group serves two purposes for Delta Green. First, it's an easy and convenient way to attach a Delta Green Friendly to an official investigation in a semi-official capacity where such an arrangement is considered to be helpful. Second, sometimes local law enforcement agents will contact Weatherman about a strange case they're working on. If Weatherman considers the case noteworthy, he would then notify Cell A, perhaps bringing to their attention a case that they might have otherwise missed. Cell A finds this arrangement to be quite useful.

Profile: Walter Weatherman
Walter Weatherman was a long-time Delta Green agent (most recently as Agent Percy) who retired in 1999. He was brought into the organization in 1980 after being assigned to a case involving a cannibalistic killer who believed that by eating the flesh of young men and women he would be able to reverse his own aging process. He killed 15 people along the Oregon coast in 1979 until finally being captured by FBI Agents after Weatherman, an FBI profiler, was somehow able to guess where the killer would strike next. The killer, Franklin Condon aka the "Coast Cannibal," is now under lockdown at the Baltimore State Hospital for the Criminally Insane. His obviously forged personal documents show him to be 42, though he doesn't look a day older than 30. Weatherman later learned the real reason for this discrepancy.

Weatherman served his country and the Delta green organization admirably until retirement. Still feeling strong and eager to continue the fight, he threw himself into establishing the Trident Group as a way for him to contribute to Delta Green's activities from the sidelines.

Weatherman lives in Mountlake Terrace, a suburb of Seattle, with his wife Cindy and dog Toby.
