Moff Jmanuel Tethys was one of the Deep Core "replacement warlords" that came to power after Admiral Daala executed the thirteen most powerful warlords and unified their forces in the name of the Old Empire. Like Foga Brill, Tethys lacked military muscle and compensated with cruelty.
Like the other replacement warlords following the Deep Core battles of 17 ABY between the New Republic and Imperial forces, Tethys' fate is unknown, though the remainder of his forces, along with the remaining forces of Foga Brill and Cinzero Gann, reformed into the Second Imperium.
