Technology & Combat Characteristics
The LV-ZGMF-X23S Vent Saviour Gundam is a rare mobile suit for Librarian Works, as unlike the organization's other machines, it is based on one of ZAFT's Second Stage Series mobile suits. Development of it was made possible as an organization close to Librarian Works was in possession of the ZGMF-YX21R Proto-Saviour. 'Vent' means 'wind' in french, and is a reference to the mobile suit's enhanced atmospheric flight capabilities. The wings, originally on the "Amfortas" plasma beam cannons, are moved to the shoulders. As a result, the wings in MA Mode are now positioned lower, allowing for more efficient generation of lift. The wings can be deployed horizontally for stability during flight in MS Mode. The 'LV' in the mobile suit's model code stands for "Librarian Vent".
The Vent Saviour also has a new sensor with improved atmospheric sensing system mounted in the head, and its armor uses lighter materials, leading to a drop in weight without sacrificing any defensive strength. The armaments of the Vent Saviour is identical to the Proto-Saviour's, and like most Librarian Work's mobile suits, it has a hardpoint for Striker Packs on its back. However, it does not have its own Striker Pack, and has to rely on Striker Packs designed for other Librarian Work's machines. One of the Striker Packs that is extremely useful for the Vent Saviour is the "Maga no Ikutachi" Striker as the Mirage Colloid particles on it can be manipulated to reduce air resistance. Even with the Striker Pack, the Vent Saviour can still transform between its different modes.
While the Proto-Saviour and the ZGMF-X23S Saviour Gundam have two different modes, MS and MA Mode, the Vent Saviour has three modes, MS, MA and Fatum Mode. The Fatum Mode is simply the "Amfortas" plasma beam cannons positioned over the shoulders with the suit's wings deployed. This mode combines stable flight performance with high attack power, and is the Vent Saviour's characteristic feature. After the Vent Saviour was passed over to Elijah Kiel, its control was customized to suit his preference and the Librarian Works' mark on the suit was replaced by Serpent Tail's. A limiter was also put in place as Elijah's body could not handle the stress caused by the mobile suit's high speed, and this restricted some of the Vent Saviour's capabilities.
History
As members of Serpent Tail (except Gai Murakumo) was in the Orb Union, Librarian Works sent out the Carbon Human clone of Gud Vair in the LV-ZGMF-X23S Vent Saviour Gundam to attack them. Gud announced his arrival to Elijah Kiel, badly shocking him. The meeting was however interrupted by the arrival of Orb's MVF-M11C Murasames and Gud left, promising that he would be back. A few days later, Gud and Elijah met again and a battle erupted between the Vent Saviour and the latter's ZGMF-1001 Elijah's ZAKU Phantom.
During the fight, Elijah successful tricked Gud and landed a few attacks on the Vent Saviour, slightly damaging it. Pleased that Elijah's skill had improved, Gud then tricked him into opening the cockpit door of his mobile suit, and hijacked it so that he could escape from Librarian Works. Gud left Elijah with the Vent Saviour, enabling him to be better equipped to deal with Librarian Works. After the battle, Serpent Tail brought the Vent Saviour to Lowe Guele for repairs and to customize it for Elijah's use. Elijah later used the Vent Saviour, equipped with Maga no Ikutachi Striker, to assist the defected Lily Thevalley clone in her battle against four LN-GAT-X207 Nebula Blitz Gundams.
