Storyline
Conquest's storyline is set two hundred years in the future, where interstellar travel was possible by jumping through networks of wormholes leading to other systems.
Following a series of internal conflicts, mankind has discovered a wormhole leading to an unknown system, Tau Ceti. Arriving in the Tau Ceti system, the TNS Andromeda, under the command of Rear Admiral Tackwhether Hawkes, is caught between a small, fast, unidentified alien spacecraft and its pursuers. After the Andromeda is destroyed in a collision with a massive alien warship, you, as the anonymous Commander, are ordered by Admiral William Halsey to investigate. With the help of Captain Thomas Blackwell, you begin exploring uncharted wormholes in order to discover what happened to the Andromeda and to find and rescue Admiral Hawkes if he is still alive.
After learning that Admiral Hawkes escaped the destruction of the Andromeda and has been taken prisoner by the unidentified alien race, dubbed the "Mantis", you penetrate deeper into hostile territory in order to rescue him. Soon, Earth and its Navy find themselves embroiled in the middle of a Mantis civil war, with the usurper Queen Ver'Lak fighting her sister, Warlord Ker'Tak. Fearing for its own safety in the face of the massive Imperial Mantis fleet, Earth assists Ker'Tak in the fight. In response, Ver'Lak assigns her chief Lieutenant, Warlord Malkor, to hunt down and destroy Earth.
During a dangerous mission to rescue Mantis warlords still loyal to Ker'Tak, Captain Blackwell's corvette is lost in a rogue black hole while trying to see what happened to a ship you send to scout beyond an uncharted wormhole. In spite of this tragic loss, Halsey and Ker'Tak order a large-scale offensive against Malkor's supply lines in the Orion Arm, assigning Admiral Benson to assist you. Benson is a good soldier, but is hardly pleasant to work with, as she fully blames you for her friend Blackwell's death.
Blackwell turns out to be very much alive, however, returning in a critical moment with yet more alien reinforcements. The Celareons have constructed a type of artificial wormhole technology, and had tested it out in the rescue of Captain Blackwell from the black hole, and used it again to transport him back to a Mantis controlled system that the Terrans are attacking. A meeting is soon arranged between the Terran Admiralty and the ruling council of the energy-based Celareons. The territory of this advanced species sits astride the raging Mantis Civil War, and the conflict threatens to engulf their systems.
The two races agree to an alliance against Ver'Lak's forces, but the meeting soon reveals a surprising and dangerous development. Admiral Halsey is shown a data transmission, sent from the heart of Terran space to the Mantis, which was intercepted and recorded by the Celareons. Vital information on Earth's location and defensive systems has been leaked to the Mantis by a Terran traitor, prompting a massive investigation to discover who has betrayed humanity to its enemies.
The ambitious Admiral Smirnoff discovers proof to Admiral Halsey that Admiral Hawkes is the traitor, apparently coerced during his captivity by the Mantis. However, Captain Blackwell remains thoroughly unconvinced, and uses his Celareon-retrofitted corvette to shadow Smirnoff's dreadnaught. Listening in under cloak, Blackwell discovers that Smirnoff is the real traitor and that he is trying to eliminate Hawkes. The depth of Smirnoff's treachery is revealed when he destroys his own ship after General Malkor uses the newly acquired wormhole technology to save him from the vessel on self destruct. Blackwell is able to retrieve Hawkes' prison pod from the ship before it explodes, and the exonerated Admiral returns to service.
It was Admiral Smirnoff who gave the Mantis the plans of Sol's defenses, in the megalomaniacal hope of ruling all mankind as a Mantis proxy following their invasion. Warlord Malkor, however, has no intention of letting the human race survive to pose a threat, and betrays Smirnoff. As a result, you and your forces find yourselves making a mad rush to defend Earth against the Mantis onslaught.
Admirals Hawkes, Steele, and Takei hold back the assault and soon take the war to Mantis territory. They discover from Warlord Ker'Tak that Malkor, nestled deep in the heart of Mantis space, is building a massive superweapon that is powerful enough to render an entire planet uninhabitable. Once completed, Malkor will go on a rampage with this new weapon and the bulk of the Mantis fleet, launching an unstoppable onslaught against the Rebel Mantis, Terrans, and Celareons.
Thus the race begins to get to Malkor's building site before he can launch this devastating weapon. After a series of furious battles, the combined Rebel/Terran/Celareon fleet manages to break through the Mantis defenses, destroying Ver'Lak, Malkor, and his superweapon. The cost, however, has been high. Earth herself has been attacked, thousands of Terran warships and several colonies have been destroyed, and mankind's casualties alone rack up in the thousands of trillions. Celareons themselves have disappeared shortly after victory, erasing all trace of their existence from Terran computers and networks, but the Terrans still left alive haven't forgotten about the Celareon's existence.
