Canopius System
The Canopius System is a section of space that is located inside the United Federation of Planets and is adjacent to the Romulan Neutral Zone. The area was a critical early Warning and supply area for Starfleet during the Federation Civil War. During Early 2406 the defenses of the area were under the protection of the 2nd Fleet, commanded by Rear Admiral Errol Heatherby.
In 2407, the USS Poseidon commanded by Captain Saleke entered the system and proceeded to destroy several early warning outposts and disrupt critical war supplies. The Poseidon, was destroyed by the USS Defender and all hand except Saleke were lost. Saleke crash landed his Escape Pod on the planetoid Alpha Serapsis 149 and would remain there for the remainder of the Federation Civil War.
Two months after the destruction of the Poseidon a 52nd Fleet Vanguard force swept into the system led by the USS Amistadt. The Amistadt captured the Defender and the 2nd fleet's commanding officer. That same task force would then proceed to the final battle of the Civil War; The Battle for Sector 001.
The Canopius System was not considered a strategically important system, a fact which was exploited effectively by the 52nd fleet.
