The Sikarians are well known in some regions of the Delta Quadrant for their hospitality. Physically they resemble humans with no outwardly distinguishing characteristics. Encountered by USS Voyager in 2371, the Sikarians were found to be a well-traveled and cultured people who placed great importance in the telling of stories. Voyager officers also discovered that the Sikarians possessed a technology, the spatial projector, that enabled them to travel distances up to 40,000 light years instantaneously. When Voyager requested the use of this technology to shorten their trip home to the Alpha Quadrant, the Sikarians refused because of strict laws which did not allow them to share their technology in order to prevent its possible misuse by others.
USS Voyager visited Sikaris in 2371 after being invited their by Magistrate Gath Labin, who had become aware of Voyager's plight. Encouraged by Gath, Captain Janeway granted shore leave to her crew, who soon discovered the Sikarians' generous and pleasant nature. Gath later demanded that Voyager leave orbit of Sikaris after having refused to allow Voyager to use a technology that would have transported Voyager 40,000 light years towards their destination in the Alpha Quadrant. Later, after this advanced spatial trajector technology was acquired by some of Voyager's officers, it was discovered that the trajector used a 20 kilometer thick layer of tetrahedral quartz in Sikaris' mantle to magnify and focus the trajector field. Knowing that they could not use the stolen trajector matrix anywhere but on or in orbit of Sikaris, the officers unsuccessfully tried to implement the matrix, which proved incompatible with Federation technology. (Sikaris is 40,000 light years from Alastria, a planet visited by Ensign Harry Kim during his shore leave. It was Ensign Kim that brought the information about the spacial trajector to Captain Janeway's attention.).
