The Mountain

The highest peak on Xia, "The Mountain", unlike all other mountains, was actually alive. It had the power to devour climbers who climbed up it's slope suddenly and without warning, which made climbing up the mountain a dangerous task. The Vortixx were expected to climb up the mountain at least once in their lifetime to establish their own bravery and ruthlessness.

The Brotherhood of Makuta once tried to ship some of the rock from the mountain to barricade their own island, but it proved to be a failure after the rock decided it liked the taste of Visorak.

Many chunks of the mountain had been destroyed when the Tahtorak and the Kanohi Dragon were fighting.

Trivia

 * The Mountain was actually a semi-intelligent "pet rock" made by Brotherhood of Makuta member Mutran who left it on Xia while on a diplomatic mission. The rock grew untill it became known as The Mountain.
