The Tetra-Luminare Group was a collection of fan fiction series with a shared universe. The group was created in 1999 and existing for 4 years until it was disbanded in 2003 to allow greater freedom for the member series' authors. Despite this there are still many common elements between the series. The group was named for the Luminaire nebula, the original location of Starbase 88 in Star Trek: The Adventures of Argus.
