He was banished from the Visati a month into the war by the Visat (The leader of the group) not because Sykin's plans were found out but because the Visat's mental capabilities were failing. Sykin was, in turn, branded with a symbol (He deems it The Devil's Hoof) on his forearm and cast out into the Real World where he later made contact with and joined the Tetragrammaton.
Time passed. Sykin seemed to change after he met a man named Jobi who led an odd band of scientists, mercenaries, and scholars named the Oriens Veritas (Which is now a faction existing only in legend as one of the greatest roleplaying factions to have come about, hehe). Sykin then surprised everyone and left the Tetragrammaton and sought to join Jobi and the Oriens Veritas in their quest to clear the black skies...
Eventually, Sykin became Jobi's First Mate. Together they were known as the Hunters for they way they sought after the Cypherites; ruthlessly but intelligently. Their greatest match was Espi, a sociopath and sadist who came from the Visati just like Sykin, who led the Masked Agenda.
Their exploits were well known, yet difficulties surfaced for the Oriens Veritas. The fellowship was small and slowly lost its veterans; at the time, new operatives in the Matrix were a huge rarity and the faction's lifeblood was running out. Sykin then requested a ship from Commander Lock and got the Guardian in return. Jobi and Sykin then left the Oriens Veritas on the surface of the Real World. Together they founded the Last Veritas, comprised of all the mercenaries they could fit on two hovercrafts. In the final days, they hunted Cypherites, then the Swordfish (Jobi's infamous hovercraft which was painted red; partly to cover the rust, partly because it was a unique thing to do) was attacked in the Real World and its communication ties with Zion and the Guardian were cut off.
For weeks Sykin kept up a search for the Swordfish and Jobi with nothing to be found. With his own crew desperately in need of support, Sykin had no choice but to abandon the search temporarily and join the Omega Syndicate, one of the oldest and most respected Zionite factions since the Truce. While in this considerably large faction, Sykin became less aggressive in the hunt for Masked Men and Cypherites and began to study the Matrix much more, rekindling his skill in philosophy and teaching others around him the meaning of many things. To this day, many know him as that wise man, though that would mean they do not know him now.
In a radical change, following an event in Sykin's life that remains a mystery, and after a failed attempt at upgrading the Guardian's complete operating system from GUARDIAN OS v3 to v7 (Thanks to stolen technologies, Sykin's operator, Nect, revealed), Sykin deactivated the core of his ship, stranding his crew in the Real World, and vanished from the Omega Syndicate. A day later he was seen conducting operations with the Tetragrammaton, and rumors said that the late Zion Captain was on his way to Zero One for reasons unknown. Shortly after, he became the Director of Intelligence for the Tetragrammaton...
It is with this that I leave you, for we have reached the present. Make of it as you will, since the old saying goes: "The Matrix has only just begun to give up its secrets."
