The Highborne Astrolabe is exhibited in the Ironforge museum.
Recovered from the undersea ruins of Suramar, this functional astrolabe was crafted by the highborne night elves nearly twelve thousand years ago. The highborne, obsessed with magic, the occult and astronomy, developed a series of ingenious apparatuses. This device provides invaluable insights into the ancient night elves' level of scientific understanding.
Though this device is labeled as an astrolabe, it is actually an armillary sphere.
