FimmRess was a male Human Sith of the Sith Empire living during the Cold War. In 3643 BBY he was dispatched to Alderaan, where served as Bodyguard of the Duke Kendoh Thul of the Empire-allied House of Thul, but his first loyalty always went to the Sith. When Darth Baras's Sith apprentice approached Kendoh, the Duke nonchalantly gave FimmRess an order to kill him, which FimmRess declined, stating that it was beyond Kendoh's authority to give. Faced with two Sith who weren't hostile to each other, Kendoh changed his attitude and went on to assist Baras' apprentice in his endeavor. FimmRess soon accompanied him to Lady Renata Alde's estate, from which he escorted the captive noble to Kendoh. While the apprentice of Baras was disabling Alderaan power generator, Kendoh used the window of opportunity to assassinate some of his political rivals and when Darth Baras called, even had the gall to blame the killing on his apprentice. When the Sith returned, he demanded Kendo's blood for trying to accuse him in the eyes of his master. Kendoh tried to appeal to FimmRess, but he refused, stating that Darth Baras' authority superseded that of Kendoh's. So he did not interfere when the Sith Warrior killed the Duke. He then bid farewell to the fellow Sith and departed for Korriban, his assignment to guard the Duke no longer valid.
