Ether drakes measure 16 feet long from head to tail and weigh around 2,000 pounds. Their lower body has a glassy sheen, their upper body is covered in osteoderms and bone wings protrude from their back.
Unlike other drakes, ether drakes are not evil and only prey on animals. When an intruder enters their territory, ether drakes create psychic mental links between each other to coordinate their defence.
