The 25ers were a group of biologists and sociologists, and when the need for a standardized time throughout New Eden was identified, they claimed that the only measurement worth considering in a space-faring age was that of the human body. The internal body clock of humans is close to 25 hours, and thus they wanted to base the new clock on that measurement.
Origins
The 25ers was a small Gallente grass-root organization led by an energetic young man by the name of Cerb-Rausolle, although he preferred the pseudonym the Astrologer. Through the efforts of the Astrologer the 25ers gained great public support, spurred on by the surprisingly big network put into place by the Astrologer. They lost the campaign to have the 25 hour clock introduced at the Yoiul Conference to the Traditionalists.
Post-Yoiul Activities
After the Yoiul Conference, Cerb Rausolle decided to use his group's influence for other causes. At that time space ship owners were required to pay huge amounts of money each year for their ship license. This was something that all the empires enforced as it provided a good deal of income for them, along with ensuring that only the cream of society could afford to be in space business. Of course, this also hampered space trade and made it difficult for the average Joe to get into the business.
The Astrologer and his organization (still called the 25ers) started lobbying for a change in the legislation. Since CONCORD was responsible for issuing ship licenses and collecting the license fees, it became the target of the demonstrations organized by the 25ers.
At first CONCORD ignored the protests, but as they became more serious it began taking notice. As it had been recently formed, CONCORD was concerned about the image it was projecting to the public and a committee was formed to handle the matter. As is often the case, things dragged on for months. All the while the Astrologer was planning more and more outrageous acts of protest, even going so far as to organize general strikes on some planets.
The icing on the cake came during the first New Year celebration, celebrating YC 1, at the headquarters of CONCORD. The Astrologer then managed to infiltrate the station's defense perimeter with a lone, unmanned cargo ship filled with explosives, which he then promptly detonated outside the station in plain view of many of New Eden's most prominent people. The Astrologer was careful not to blow the ship up so close as to injure any of the guests, but his message was heard loud and clear. Two months later new CONCORD legislation abolishing the license fees was passed by all the member states.
Later Years
The Astrologer, now a fugitive after his stunt, quickly became a living legend. The 25ers organization was dismantled and the Astrologer lost his status as the champion of the people. But his name is not forgotten, nor that of the 25ers, and every now and then a new group is formed somewhere in the world of New Eden, proclaiming itself as the successor of the old 25ers, dreaming of reliving the times when the little men defeated the big guns.
