Marcus Cromwell
Son of the famous Richard Cromwell - the first spaceborn human. Marcus was born the same year the Martian wormhole was discovered. When he was 10, the colony ship, known as the Noah's Ark, was launched with Richard Cromwell as captain. After the apparent loss of the Noah's Ark along with Richard, Marcus did not lose the thirst for space exploration he got from his father. When he was old enough, he enlisted in the Federation Fleet, only to find himself in the middle of the Martian War, as colonies and the Megacorps declared independence from Earth. Marcus Cromwell's ship was ambushed and crippled near Phobos, and he spent 10 years in suspended animation, waiting for someone to find him. Finally, he was found and revived to find that Earth lost the war. The victors proclaimed him a war hero nevertheless. Eventually, SpaceTech made Marcus an offer to command one of their Heavy Corvettes, which he accepted and was given the Stiletto.
In the mission of Shukenja Base Beta around planet Pluto, Marcus was given the command of Angelwing, the spaceship of alien origin he discovered in the previous mission. Reaching Shukenja base, he encountered an unidentified object - later known as a Mechanoid - stayed calmly near the base. He also discovered another wormhole similar to the one discovered around Mars many years ago. While Marcus and his crew were analyzing Shukenja Base Beta, the unidentified object suddenly attacked their ship. In their confusion, something had entered the ship's main computer system and identified herself as Angel, the AI of the base. Angel activated the shield system of Angelwing and told Marcus to jump into the wormhole, because she could not protect the ship for a long time. Marcus and his crew had no other choice but to follow Angel's advice to enter the wormhole, only to find a shocking reality on the other side of the universe they found.
Angel was "born" as Tenshi, an illegal A.I. designed to operate the Shukenja Beta base near Pluto, owned by the Kissaki Syndicate. When Tenshi was uploaded into the base computer, a dormant A.I. left there by the last Creator merged with it and began to grow. Due to Tenshi's ease of interfacing with the Angelwing's systems, the Syndicate placed it in charge of the facility. After the Mechanoid attack on the base and the Angelwing's arrival under Marcus Cromwell's command, Tenshi uploaded herself into Angelwing. By that time, the alien part of her became more and more dominant, and the new personality decided to call itself "Angel" ("Tenshi" is Japanese for "Angel"). While initially a subservient personality, Angel eventually begins to question and disobey Marcus Cromwell's orders.
 Rear Admiral Arthur Norbank
The Noah colony admiral in charge of the main offensive against the Gorg Empire. While he is by no means incompetent, his arrogance and distrust of almost everything tend to result in, at best, very costly victories, and at worst, embarrassing defeats. Norbank became famous as a captain when he led the newly-created Noah fleet in their first battle and victory against the Gorgs (mostly because the Gorgs were expecting the Vardrags). He is the de facto comic relief of the game as the player must, on several occasions, pick up after his mistakes, assume command when he is incapacitated, or even rescue him.
 Commander Sweetwater
Despite what her name suggests, Commander Sweetwater is anything but sweet. Living most of her life among the Ghosts has left an imprint on her personality. She constantly insults Marcus Cromwell, Angel, and the Angelwing, questions their abilities and motives, and obeys orders only reluctantly. Unfortunately for Cromwell, she soon proves to be indispensable to his cause, as she is the official Noah liaison with the Ghosts and is the only human, capable of operating the Ghost cloaking device fitted for the Angelwing.
 Captain Francis Delorian
Francis Delorian and Marcus Cromwell were friends before their paths split. Delorian joined the ISA and Cromwell signed up with SpaceTech. During Cromwell's mission in the Jupiter sector, Delorian's ship was attacked by two OSEC Longsword-class Heavy Corvettes. Because of Cromwell's interference, Delorian survived the battle and later joined the crew of the Angelwing on its mission to the Shukenja Beta base near Pluto. When the Noah Colony Admiral Anderson gave Cromwell command of his own small battlegroup, Delorian took command of the Tactical Destroyer Sparta.
