Crystalline factorier

This void - floating entity, which is very intelligent, has appeared all over the universe for some reason, and has socialized with minecrafter kind. They have a large crystal growing out of their back, which appears to be moving across conveyers under its protective layer. The crystals go up to its head, whichhas a big brain, but also is connected to a furnace near its heart, which smelts the crystals and then puts them into small boxes at its feet. No one knows how much space is in the boxs, but some say portal technology is involved. Though it has no facial features except the exhaust ports, it, can still speak, hear, sound, feel, and it can even taste foods, by putting them in the exhaust port. Sometimes, if threatened, they will release the crystals in the boxes, and combine them, causing a tiny crystal golem to protect the entity. (To see the actual conveyers, remove the outer layer. Also, please do not republish this skin, as I spent a while on it. Please.)
