And wraiths. From the planet in enterprise, they are non-corporeals, but they are also shapeshifters, and amazingly talented ones at that. They have a worm-like natural appearance, but rarely show it, preferring instead to show up to at least friendly people as whatever they dream of seeing, and to enemys, they appear as the environment, such as a tree-branch, or a rock, or whatever would fit with the environment. There were people who hunted them. 65.188.241.8 21:19, 17 January 2009 (UTC)
