Well, obviously, I can still use it, regardless of what form I might take.

[Ardyn can hardly be expected to identify a Garlean, but this, apparently, is what one looks like.]

Fortunately, by that point the Garleans were already developing weapons to compensate for their inability. A few nudges here and there and their magitech has blossomed to a height, at least in military matters, comparable to my masterwork of Allag. In a more immediately personal sense, I've a solid hand on a gunblade and a keen mind for tactics, and that served well enough to make the heir of the Galvus family into an Emperor.
