Eclipse

Eclipse is the primary weapon of Nocturne Argentum. It is an incarnation of the Argentum Family's Nameless Blade.

It is classified as a Plasma Dust Combined Blade (PDCB), made up of an assembly of three distinct blades. When the auxiliary blades are removed, the base sword can project Plasma Dust on its edges.

Eclipse Prima
The first version of Eclipse, retroactively known as Eclipse Prima, is a fairly large one-sided sword that bears resemblance with a falchion and a messer. Its blade has a subdued gray sheen with a black fuller. It has a large ornate silver-accented cross-guard housing a complicated mechanism.

Eclipse Ultima
Modifications over time culminated in Eclipse Ultima, an ever-evolving final form. The weapon's material has been reinforced by replacing it with a refined steel alloy that provides rigidity.

Eclipse Ultima is made up of three swords that magnetically interlock to form a combined weapon. When complete, the sword's profile is unchanged from its previous incarnation, but the weapon's inner workings have been expanded upon. The weapon's outer shell can be removed, revealing a customized double-edged sword capable of projecting Plasma Dust on its edge.

History
Nocturne received Eclipse when he turned 16. It is an incarnation of the Nameless Blade. It's predecessor, Astra, was reforged and rebuilt to create Eclipse.
