Warping is a form of magic. As a command, it’s probably similar to the Warp Spell of past games. As a spell, it “allows the party to teleport between different floors in a dungeon or to escape from battle”. Noctis use warp strike to do both. After throwing his weapon up to a “point-warp”, he can technically teleport to a different floor. Technically, you can escape from battles the same way.
Where does Noctis keep his weapons? The Armiger. This arsenal summons spectral versions of the royal arms around Noctis. But how does it work? The magic used is the Void:
The Void—as it is referred to as an actual, physical area in space—often takes a form chosen by its “wielder” or current denizens, though it is often seen against a backdrop of pure darkness or celestial atmosphere. The term “Void” is also used in reference to the power to distort, or remove entirely, large parts of space. This is the most present form of the Void in the series.
As a thing, the Void is able to “remove entirely large parts of space”. But it also works as a storage unit. Consider all of the places that end up in the Inter-dimensional Rift through the powers of the Void:
- Walse
- Istory
- Moogle Village
- Lix
In Final Fantasy V, Bartz, Lenna, Faris and Krile can travel through the Inter-dimensional Rift, and travel out of it. The party can reach the entrance through the Warp Spell.
In the same way, Noctis can dive into the dimensional storage, which acts as a warp to certain points. These points are pockets of the Void, scattered all around Eos. But in this sense, Noctis can control the power of the Void, in a similar way Exdeath can. His bros are unable to warp. Not only are they not of royal blood, but they can’t control the magic in this sense.
