Considering that when we were known as Viking Nation or Valhalla we were the main force because of clan mergers of Vengeance and Reincarnation.Reincarnation brought most of the members but we still went under the name of vengeance.
During said time we had probably close to 80 actives, all being on vent. The core group of pre-merge vengeance members was round about 30. Along with other clans we controlled a good portion of the island of Nif, with are enemies being Ship Wrecked Pirates and Scary Bad guys at the time. We were a alliance of 4 main clans strong (Not counting the little clans that lived out of allied cities)
The second was when we joined the Cairn alliance. We were still in the merge, which later changed (Most of the members that split are actually going to be in this game as well, they are in the clan BAC or Bad as Can. They were the higher ups of Reincarnation I believe) The leading clan of Cairn known as Sinister went under new management that made the clan fail so we jumped ship. Im not 100% sure of the details that happened during are departure from the Cairn alliance as my Alienware had taken a massive dump and didnt work at the time.
--Edit--
Im sorry, I have misinformed some. Reincarnation didn't even exist when this merge happened. They disbanded shortly before. Are merge was actually that of multiple clans but the members of what is now BaC were known as Project Mayhem when they joined us.
Sorry for the misleading, I had just came back from a break for college when this was going on, I got my information crossed.
