Magic

The Aura, also referred to as the Light Force by Picori and Blood of the Gods by the Ancient Hylians is the magical source of the Oocca's power. It physically manifests as brightly glowing blue energy.

Characteristics
The Aura is an energy conversion that draws power from the Spirits of the Sacred Realm. It can give life to the inanimate and is used to construct everything from Ooccas' bodies to their robotic soldiers.

Though it can manifest independent autonomous statues, many such as the Oocca choose to bound those constructs to remote controllers, taking the form of Dominion Rods. These staffs are usually not bound to just one statue, with the exception being Koloktos' Dominion Rod.

It can also be channeled by the Oocca for "Cleansings" in which the power of the Aura is focused into a gargantuan blast of energy fire by a structure mounted on the bottom of the City of the Sky which obliterates anything it touches in a massive blast of blue fire and upturned earth, followed by a powerful but nonlethal cascade of blue energy as a sort of aftershock. All that remains from its effect is a crater of molten glass.

It is likely that the Cobble, Fairies, Guardians, Wizzrobes, High Zora, necromancers and creators of Armos draw their power from the Aura, though nothing has been confirmed.

Trivia

 * The Dominion Rod used to command Koloktos is based on the Royal Dominion Rod from Hyrule Warriors.
