Seyugi was a space object situated within the Seyugi system. This system was found in the Arrowhead region, which itself was located in the Slice area of the Core Worlds. Around 22,000 BBY, Seyugi was within the territory of the Galactic Republic.
The name of this astronomical object was the same as the Seyugi, a group of people who once lived on the Core Worlds planet called Recopia. By 980 BBY, the Seyugi population had created the Force-using group of assassins referred to as the Seyugi Dervishes. In time, the Seyugi Dervishes expanded across the Core and established themselves on the Seyugi astronomical object.
The reference book The Essential Atlas, which was released in 2009 and written by Daniel Wallace and [Jason Fry], first featured Seyugi and placed it in grid square M-11.
