Golden Peaks

The Golden Peaks are a landmark in Ninjago where the Golden Weapons were created.

History
It's assumed that the First Spinjitzu Master created this place in order to make the Weapons of Spinjitzu for good. He then sealed the Sword of Fire in the Fire Temple, the Shurikens of Ice in the Frozen Wasteland, the Nunchucks of Lightning in the Floating Ruins and the Scythe of Quakes at the Caves of Despair.

Lord Garmadon then combined the four Golden Weapons into the Mega Weapon, saying "Now to destroy the Ninja...once and for all!!"
