Star Wars Omnibus: Tales of the Jedi, Vol. 1 (Various)

Star Wars Omnibus: Tales of the Jedi, Volume 1 collects four stories, set ~4000 years before A New Hope:

The Golden Age of the Sith
Jori & Gav Daragon are down to their last chance.  Hyperspace navigators, they explore the galaxy seeking safe travel paths.  One random jump takes them to an uncharted corner of space, where they find the fabled Sith Empire, a system inhabited by fallen Jedi who fled there generations prior and enslaved the local populace.  The Sith are divided over the arrival of the newcomers- but newly-minted Dark Lord Naga Sadow sees this as an opportunity to extend Sith influence and dominate the galaxy.  He lets Jori go back to the Republic, secretly placing a tracer on her ship.  She will show him the way . . . and the Republic will soon be in flames.

The Fall of the Sith Empire
With Jori's unwitting assistance, Naga Sadow finds the way to the Republic and launches his assault.  The Republic will need every means at their disposal to succeed . . . and help arrives from unlikely sources.  Defeated, Sadow takes his last ship and retreats to an uninhabited Yavin 4 . . . where his Massassi will build temples that will one day house a fledgling band of Rebels.

Ulic Qel-Droma and the Beast-Wars of Onderon
Summoned to the half-savage Onderon, Ulic and his brother Cay hope to bring peace to the war-ravaged world.  But all is not as it seems, for a long-dead Sith, Freedon Nadd, is entombed here, and has influenced generations in the dark side.

The Saga of Nomi Sunrider
Her Jedi husband murdered, force-sensitive Nomi Sunrider and her daughter fulfill his journey by delivering valuable adegan crystals to Master Thon.  Left with nothing, she starts training with him, but spurns any aspect of violence.  When a local Hutt hears of the gems, he sets his henchman on their location.  Nomi must make a choice . . . and with it, decide her destiny.

Review
These are classic Star Wars tales from Dark Horse Comics, looking at the history of the Jedi thousands of years before Luke Skywalker.  The stories are interesting enough, though the pace is lightning-fast and dialogue poor.  Recommended for fans of the 'original' (pre-Disney) Star Wars universe.
