Darth Krayt's holdouts

Following the defeat of Darth Krayt and his Empire in 138 ABY, several holdouts of the One Sith Order and the Empire continued fighting. They were isolated in different pockets of the galaxy, such as the Outer Rim Territories. The holdouts gave the Galactic Federation Triumvirate much grief during it's early years, but were ultimately defeated by the Triumvirate Military. The One Sith Remnant was mainly not unified, but a united faction was under control of Darth Nihl.
