The Meridians were a group of about 30 humanoids who were the descendants of an expedition that was stranded on the Gamma Quadrant planet Meridian "millenia ago". As their entire planet shifts between dimensions, they spend sixty years in a non-corporeal state, followed by a shrinking amount of time (about two weeks as of 2371) in normal spacetime. While in physical form the Meridians were humanoid in appearance, with distinguishing markings near their eyes.
