Spiresia's surface is dominated by colossally tall structures built into the rocky terrain, all constructed long ago by forgotten architects, all beneath a strange amorphous blue sky. The spires are home to a diverse array of creatures that have adapted to life high above the ground. The people of this world have mastered the art of climbing, using advanced gear to do it and building their homes and settlements within the rocky spires. Rumors abound of ancient secrets hidden deep within the spires, waiting to be discovered by intrepid explorers.
