The Sethnor is the name given to the earliest Eldar inhabitants in the Agrippa Sector. It is also the name of a planet and sacred Eldar shrine guarding the Sethnor Gate.

Today the only remanents of the once great civilisation are the guardians of the Sethnor Rosia Shrine and the fallen splinter tribe of Dark Eldar known as the Drak Seth.

It is said that the Sethnor guardians number in the mere hundreds, representing the last of a great race that are on the verge of extinction.
