*In their natural form, The Spirits of the Coast Salish Indians are humanoid aliens, with tri-flanged breathing organs covering their faces. They have psychokinetic powers of healing, can alter their forms at will, and can telekinetically move objects and people. In the episode "Spirits," the Stargate team visits The Spirits' home world and discover a new metal called Trinuim, a hundred times lighter and stronger than steel. The Spirits thwart SG-1's efforts to mine the metal and bring it back to Earth.
