Between Golden age champions and the recent discussion of comic decades I've been thinking of a sort of timeline. I don't actually have a campagin or city to use it in, though I'm thinking a legacy type campaign. While it lacks detail the broad strokes are pretty much done, so I figured what the heck. I'd let people look and decide if I need a rethink.
The Age Of Mystery
As the 20's dawned a secret war broke out of the streets of Blank City. It was a time of great growth. However while there were many technical wonders created not all were in safe or even sane hands. Modern travel brought many ancient secrets into the city, even those that should have stayed buried. And the passing of so much of the old guard in the Great War left room for innovation, but not every bold new philosophy, or leader had societies best interest at heart. Many of the heroes who rose to meet this challenge activites, if they ever really existed, are now urban legend. But there was a time when criminals trembled at the mere mention of names like the Owl and Dazzle Dame. Though an explosion in masked criminals is definitely written in the papers of the time. Exactly what crimes people like the Gentleman Skulker and Baron of Crime commited may never be known. But the city was a lot safer after they were arrested. But there were those who stepped into the limelight. People argued if Maras the Mystic was just a god magician or had actual mystic powers. No one argued how often he was there when a criminal was caught. And though some reports in the files are rather odd. Homicide Det. Derek Grant 's battles with organized crime like the Shadow Council and the first version of the Marintas inspire police cadets to this day. Perhaps most notable was Thomas Telblum the Techonligcal Crook Cather. Who's patents are responsible not only for helping the police solve some baffling crimes, but been the birth of three different tech companies. Though even the most unaware citizen became aware of this war at the battle of Burton's peak. Someone calling himself the Electric man interrupted radio broadcasts to declare that he was truly Tesla's greatest rival. And to prove it he was going to use the death ray Tesla failed to invent to electrocute the city. Overnight a large strange structure appaered on Burton's peak. The cops who went to investigate were killed by a gathering of the cities most notorious criminals. An all out assault led by Det. Grant, Telblum, and supposedly the Owl attacked and the structure blew up killing most of the assembled.
The War Years
However conflict was soon to break out in Europe, and the city began to prepare for the inevitable conflict. Though far from the front lines, the city was still a major industrial and technological hub. Telblum closed his lab and opened a factory forming Telblum Inc. and going to work for the war department. That was one of the first but hardly the last retooling done in the city. And when the conflict broke out dozens of young men and women went overseas. Leaving it vulnerable to the forces of crime, and foreign agents. And unlike during the age of mystery these people exhibited powers the like of which the world had ever known. Which led to the government starting the Protectors initiaitve to give the country more powered guardians. These were countered by Nazi agents like Todesadler and the Black Spider whose acts of spying and sabotage nearly crippled war production. While black marketers and organized crime like Jackpot and the revived Marintas crime group siphoned millions. Fortunatly the city was defended by Protectors initiative operative Golden Shield, and freelance heroes like Pride and Virtue.
After the war was a relatively quiet time there were a few communist infiltrators like Cold Heart and the People. But nothing like during the war.
Saw a rebirth in superheroic action. Though not without the political upheavel of the day. Heroes like Groovy who could only use his powers when high of illegal drugs gave city hall a few headaches. After the closing of Telblum Inc after the war, the patients were acquired by Blake Reardon who founded Reatec, and soon after the armored Titanman showed up. A new Dazzle Dame appeared though unlike her predessor she didn't just use strobe lights to blind foes. But where their are heroes their are villians the Iron duke and his iron legion made several attempts to take over the city. And a new force in the underworld calling itself the Horde battled Martintas for control of crime.
O.k. like I said kinda sorta. In each age of course a more detailed list of heroes/ villians and their abilities would need be made. And depending on what decade I set the campagin in I'd need a 70's etc section. And the 60's section needs work. But I don't think I've gone too far a field here.
