Lost Tribe of the Sith (e-book anthology, NOT the comics series by the same author)

These stories start right after the Harbinger is thrown off into hyperspace in the prequel story to Crosscurrent, which eventually sets the stage for an adventure in the Skywalker era.
The Harbringer's sister ship, the Omen crashes on a new, unexplored world with a Sith crew, originally sworn to fight for Naga Sadow during the Great Hyperspace War.
These Sith continue during the time of Exar Kun's reign, but though I do not know at this stage in my reading, they may not interact with the Sith based on Yavin at all, but be an entirely separate colony.
Then their saga moves on to the Mandalorian War era.
I believe the species aboard Omen's crew were a mixed lot, that included Sith amongst many others, enslaved or who sought opportunity originally pledging themselves to Lord Sadow.
John Jackson Miller is an excellent author and I loved his KOTOR comics. His penmanship of a traditional novel seems incredible as well. He also writes Knight Errant for fans of that series (which I have not yet gotten to either).
