Daniell Kenobi Solo's Sith were a group of Force-sensitives—either fallen Jedi or recruited ones—who followed the orders of Daniell Kenobi Solo.
They were formed in 3,997 ABY under the instructions of Darth Abeonis and several other Sith Force ghosts. When they attempted to takeover, Daniell blasted them away and took over, which was exactly what they wanted. Since she had destroyed duplicates of the long-dead Sith, they had drawn her even closer to sustaining herself permanently with her anger.
