DiabolicalMech, also known as the Mysterious and the Unseen One, first Guardian to be awoken by Asymptonic in the early days of the First Age. Unfortunately forgotten by many Lokans, the mysterious Guardian had passed back into the wizard's sleep during the first world.
DiabolicalMech was the eldest of the Guardians, and the most mysterious. He was completely covered by a black cloak, so that only his eyes could be seen glowing beneath the edge of his hood. Over his shoulder he wore a multicolored sash, and was very tall and broad-shouldered. He was seen very rarely, but would occasionally appear to warn Slicers against dark magics.
