The Tobay was an Adz-class patrol destroyer. This vessel belonged to the Grand Imperial Navy, the supposed Imperial armed forces that defended the fortress world of Prakith situated in the Deep Core under the command of Warlord Foga Brill.
The Tobay, while relatively up-to-date, wasn't as new as the cruiser Gorath. Furthermore, its systems weren't as well-maintained, a fact that greatly irritated Captain Gegak. Other key members of the ship's company included Frega, the navigation master, and Nillik, who served as the sensor master.
During 17 ABY, the Tobay, in conjunction with the Gorath and the frigate Bloodprice, came across the Teljkon Vagabond. While the other two ships were obliterated during their attempts to seize the Vagabond, the Tobay remained intact. Ironically, this survival might be attributed to Nillik's inability to effectively track the alien vessel due to his unreliable equipment.
