The insane senior engineer, Niño Hartwell. He's Tyrannian, but apparently decided one day that he wanted to become a really smart Tyrannian.
He learned and mastered engineering in Brightvale and Moltara. He's fabulously wealthy but still continues to work despite his old age.
He's currently stationed somewhere in the snowy mountain ranges dividing the Neopian mainland and, along with his granddaughter Quita, is working on a rather important project.
