The North Pole

At a glance, an utterly unremarkable plain, dotted here and there with small lave lakes.  You would never guess that it was the orbital axis of the planet.  However, it is quite close to Aluxa, and recently construction has begun in the area.  Small, squat buildings form a circle around the pole, spaced to form a ring almost twenty miles in diameter.  At the exact center, excavation has begun.  A massive, spiraling pit, already reaching down nearly five hundred feet.  Crews of matoran carry the rubble to the refineries of the ring, which begin their work.  Meanwhile, at about fifteen places on the ring, construction begins on something that seems much larger.  Blocks of a shining, unidentifiable metal are carried by matoran from the refineries to the construction sites, where toa wait, using a combination of heat and metal control to shape the blocks into additions to the construct.
