A first in the series, the player takes full control of the spacecraft. The ship is one of five assigned to scout new frontiers under the First Expeditionary Batch and authorized by the USTA. The Calnus contains a flight deck where the player can pilot the ship to various planets throughout the game. Further inside is the spacious recreation room where the player's teammates hang out and the conference room, where the player can gather the crew to come up with new ideas for Item Creation. The crew's quarters are where all the crew sleep and rest during space travel. A battle arena is also available for the player and his teammates to practice combat. The ship is one of the sources of Private Actions that can occur in the game.
