Within a month of becoming Prince, Robert Grimshaw proved to be a double dealing scoundrel by cutting a pact with the Tremere who Sebastian and the Brujah hated. When word of this pact reached Sebastian he immediately started to gain support to oust Grimshaw. Soon Sebastian had the physical force necessary to remove Grimshaw and half the Primogen. Promises of clashes to come at midnight had the Grimshaw camp scurrying to prepare defenses while Sebastian made his final political move. He would become Prince and with a firm hand bring peace to the City of Atlanta, even if it meant killing almost everyone. Grimshaw was quickly removed and thus began the First Reign of Sebastian Young as Prince.

Sebastian took no rest and began to secure his position right away. A tough stance of intolerance when it came to breaking the traditions and many bloodhunts proveed he meant business. Shortly after assuming the Princedom his Seneschal disappeared, never to be seen again. Some say the Seneschal disobeyed Sebastian and he was slain for that. Others say it was the Harpy Courtland, clearing the way for him to take Seneschal. Sebastian moved with swift and devastating efficiency against neonate, ancilla and elder alike. The Bloodhunt on Lady Augusta, a very well liked figure, sparked some to rebel against Sebastian and take up an Anarch cause. The war began and many of the anarchs were slain. Just as Sebastian was planning the downfall of the Anarchs, the Camarilla interceded and sent three Archons to take over and bring the city under control. The two factions were told in no uncertain terms that the traditions would be observed. This ended the First reign of Sebastian Young.

The Archons stayed for three months cleaning up some Sabbat packs and punishing those that would not follow the Traditions. Sebastian's own progeny Gunter, was put down by Sebastian because of how violent and unstable Gunter had become. The Archons left as abruptly as they had appeared telling Atlanta that if they ever had to return it would be Hell on Earth. They also said it was up to Atlanta to determine their leadership. At this point Sebastian stepped forward and took the Princedom again. Heeding the Archons words he began a hard-line policy of zero tolerance. As it was in times of old, there was but one punishment for breaking the Traditions: DEATH - swift and final.

During Sebastian's second reign he eliminated most of his opposition by cutting secret deals and creating the first true Primogen. An organization of the most powerful Kindred in Atlanta including Arik of Clan Gangrel, Scavus of Clan Ventrue and Nathaniel of Clan Toreador. Between them they controlled 75% of the coteries of the city and could promise stability.

In a series of events that still puzzle scholars and common folk alike, Sebastian declared Atlanta an Anarach City and demanded that representatives from the Justicars come meet with him. The Camarilla was in a transitional period, and movements among the highest ranks had trickled down and were negatively affected Atlanta. Sebastian unwilling to have his reign negative affected by morons in Europe, split ties with the Camarilla in a maneuver to isolate himself and Atlanta from the problems being experienced within the Camarilla.

Shortly thereafter, Sebastian disappeared from Atlanta. The exact situations of this disappearance being a total mystery to all, including his childer. Rumors that Sebastian was drawn up to become an Archon were not confirmed. Rumors that he might have been slain by Camarilla Elders as an example to other cities quickly filtered back down. All that was know was that Sebatian was gone and that the Camarilla Archons had returned and appointed a Toreador Prince. Thus, began the reign of Prince Augustus.

Almost a year later, Sebatian returned to Atlanta. Now a confirmed Archon under the Brujah Justicar, Sebastian's return answered many of the questions that his disappearance had left. His return was short and marked by a sudden invasion of Sabbat infiltrators and several War Parties. Sebastian quickly reinforced several local archons and gathered together neonates and Ancilla in an attempt to limit Sabbat expansion in the area. His actions clearly were a key in Atlanta remaining Camarilla territory. After a few short months, Sebastian and assembled Archon forces moved to Texas to move against Sabbat incursions there.
