[Ganondorf used his magic some time ago to imbue a regular Snowtarman so that it strengthened into a Snowtarman Deluxe. Magic mixes well with PSI, Giegue found. So this might be worth an experiment in itself.]

Animating an inanimate object is a basic skill. But it's possible to empower them in the process, granting them a degree of sentience and quite a lot of strength.

That's what a Guardian is, an animated object that has transcended, becoming a force to be reckoned with. I doubt it can defeat Tirek, but it will fight him as long as it needs to in tandem with our other defenses.
