The Mute were a brilliant people, and the zenith of their advacements was during the Mute Age. Also known as Fart Tech, the deaf Mute were not aware that all of their technology made fart noises in one way or another. Their tech was powered by Energy Stones, the crystalized soul of a sentient being. The grander the soul, the greater the threshold to store power within the Energy Stone. They utilized this in a number of ways, but one of the most applied functions was to power totems. Mute Totems could draw power from up to three Energy Stones to create effects in the surroundings, like water and fertilize grass, create light, lessen/increase gravity, create a barrier or act as a turret.
Once Soul Stones were mastered, they took the tech further and constructed a wonder to harness the soul power of the Skaards through out Auolun, to which they were successful. These Power Cores gave them access to a nearly limitless source of energy, and they built their cities and culture around the Power Cores. The Mute were scientific in their society and minds, and recognized the Skaard not as some god, but a very powerful creature, with the mysteries of its being to discover. As a creature, they found they had to feed it, and so it recieved a steady diet of people, which the Attamikarri spun as sacrifices to the Auolean masses.
