Ice-Gyre

The Ice-Gyre is a Weapon that creates the Frostmarch Glacier when activated by the Grand Frost Mage, using an Unknown spell.

Creation
It was believed that the Grand Frost Mage forged this weapon with the assistance of the Magika Energy that resonates from the Tower.

Each Gyro is crafted from Dwemer Metal, making it incredibly ressistant to the Weather the Weapon creates.

The Spell used to activate was believed to have also been created soley by the Grand Frost Mage, Who assumingly had the ability of an Aedra.

Operation
The Ice-Gyre is operated by a single spell, Only known to the Grand Frost Mage, who used it numerous times during the Frostmarch.

The Spell is cast into the Centre of the Gyre, which will catch the Magelight-shaped Magika, and begin to spin. The spinning is believed to be the result of building up a higher distance firing rate, which means that if the Target is farther, the operation time is extended.

The Ice-Gyre will fire, and the Spell will have vanished, causing the Ice-Gyre to slowly stop rotating.

There are also two Alligning Gyro's, to help aim around the Spire's offshoot.
