CSF-S3dA/NU-023 Arodnight

Being Developed from Castel GTs and Alex’s Harbinger, the Arodnight was the prototype version of the Castel GT-II Frame. Sharing a similar design to the Castel Limited Production Frame, it is highly mobile and versatile on the battlefield. Most notably, by using data gathered from the Harbinger, the machine is usable with the NU METACOM System. This allows Dom to make full use of the Arodnight’s maneuverability, especially with the disposable heat sabers he (possibly) gains from NOVA Team’s Sabre.

Armaments
- Anti-Armor Smart Saber: This version of the Anti-Armor Saber is much larger and can be used by both one and two hands. While the design of the sword was rarely used by most Castel units (who usually used the Anti-Armor blade), a handful of these were still produced for commanders. The one used by Dom was given a more hollow blade for a faster swing speed, and was engraved with his personal insignia. It also had the unique feature of a movable blade which, by the use of a semicircle-shaped rail (that also serves as a hand guard), allows the weapon to be wielded both forehanded and backhanded. It also features a hollow body that can catch enemy melee weapons and break them with a twist. (Ian would learn this the hard way.) This weapon would eventually be replaced by the Disposable Heat Sabers taken as a gift from Neptune Base (or not).

- Disposable Heat Saber: A prototype Ace Weapon similar in shape to the Anti-Armor Saber, it is unique in the fact that it features a detachable and replaceable blade. Spare blades are stored in the side skirt armors, with the hilt clipping to them after the last blade is disposed. Since the hilt contains the generator powering the heated edges of the blade, it is easy to replace. When a blade is detached, it can be set to explode by a command set during the detachment sequence. The superheated chemicals will become unstable without the generator powering them, and a miniature concealed explosive will detonate. Since there were two copies of this weapon available in the Supply Warehouse, Dom chose to dual-wield them like he did with his Castel GT Custom.

- Nanolaminate Expandable Shield: The shield of the Arodnight is multi-layered, with its top layer sliding out when deployed. This keeps the system compact when not in use, and defends just as well as a Standard Shield. It is usually mounted on the left forearm when in use.

Special Equipment and Features
- FrameBreaker Optic: Unlike the FrameBreaker Visor used by units such as the Juggernaut GT, the Arodnight did not have access to a complete version of this system. Instead, the remnants of a FrameBreaker Visor was scavenged from a Juggernaut GT and integrated into the Arodnight’s incomplete right eye. While using this partially complete system, Dom can make out most of an enemy’s exposed frame, but not all of it. The system’s tendency to give the pilot tunnel vision is a lot more prominent than normal, meaning that it is less accurate and can cause Dom to miss his targets. When activated, the right eye of the unit glows a bright crimson apart from its usual yellow.

- NU METACOM System: When a NU METACOM System was discovered in the warehouse captured by the LCR (likely a keepsake held by the ML), it was integrated into the Arodnight during its construction. This allowed for Dom to attack at a far greater power than Cecelia and Alex combined, even going as far as to score a kill on ace pilot Lena Cassidy. This system would be used by Dom until it was refitted into the Excalibre (as the Arodnight wasn’t powerful enough for him).

Trivia
- Due to a scarcity of resources, the bulb cover shielding the Garrisai's right eye was removed but never replaced, leaving the circular socket exposed. It gives an ominous bright glow in operation. While the normal eye glows yellow, the incomplete eye glows red.

- The Arodnight is most inspired from Barbatos Lupus of Gundam IBO.

- Arodnight is actually a misspelling of the legendary sword Arondight.
