The first game world group to bear the name "Sidus Noctis" was formed in Lineage2 by Arclone and Shadowcat. They adopted a set of rules known as the Sapphire Tablets and developed a hierarchy with Arclone as the clan's "Lord" and Jgirl as it's "Lady".
In August of 2005 Nocti Prince Moriagane of Lineage2 moved into the world of Matrix Online as "OpenSorce". Within a few months OpenSorce, Vegetto, Kaipo43, ShadowRogue, Arlandria, Noxander and several others initiated an Organization like none before. As a tribute to the old Lineage2 clan, OpenSorce dubbed this new organization "Sidus Noctis".
Although the two separate groups bore the same name, they varied in many ways. This new Organization had no "Lord" or "Lady". The were lead by OpenSorce and inspired by thier Queen Arlandria.
As the Organization grew this new incarnation of "the Nocti" became something altogether different than any group to ever use the name. Rather than adopting the many rules of the Lineage 2 clan, the new Nocti embraced two rules and two rules only: Recruit the Strong, Destroy the Weak. At one point we were the single largest faction in all of Matrix Online. All servers combined.
As of this writing, the Nocti (as envisioned by OpenSorce) occupy at least 6 simultaneous game worlds: World of Warcraft, Matrix Online, City of Villians, City of Heroes, EVE Online and Star Trek Online. With it's many loyal members the Nocti continue to grow and flourish.
