Trak Blackthorne

"There is a hidden base inside the asteroid field, where great-grandfather Trak headquartered a secret Mandalorian movement, contacting his Mandalorian allies and holding meetings."

- Cadden Blackthorne to Faarel Blackthorne

Trak Blackthorne was once a Jedi Master, but the dark side claimed him and he abandoned the Jedi Order. He founded Blackthorne Enterprises and used the Udine System as a secret base for his Mandalorian allies, secretly collaborating with them to stage various conflicts throughout the galaxy.

History
"Your great-grandfather was a dark Jedi, who coherted with Mandalorian mercenaries. He often hid his presence in the Force when he was associated with them in the few times he fought alongside them."

- Faarel Blackthorne to Cadden Blackthorne

Trak Blackthorne was born into the lineage of the Blackthorne Family, and as such he was identified early on for his ability to use the Force. Like his lineage, he entered the Jedi Order and grew into a strong-willed and dedicated Jedi Knight, and eventually a Jedi Master.

However, at some unknown point of time, Trak was seduced by the dark side of the Force, and left the Jedi Order. He founded Blackthorne Enterprises and, through it, he conspired with the Mandalorians in their efforts.

The details on Trak's death remained a mystery, but he did leave behind a legacy for his descendants to follow.

Legacy
"Trak Blackthorne is way beyond his days. But that would mean that all three of these men are related. Which also means that Clan Blackthorne is back amongst our ranks."

- Locke Rekkon to Gandon Belak, on Cadden Blackthorne and his sons, Jerik and Guan

Despite the fact that Trak died, he left behind for his ancestors to eventually find several legacies. First was a cyrogenically-frozen army, which Cadden Blackthorne would later awaken. Aside from that, he left behind his own personal set of Mandalorian armor, which went to Jerik Blackthorne, whom later discarded it at an unknown location. Left behind was also an aged and defective pair of crushgaunts that came under ownership of Togra Locklear. An ancient beskad was also left behind, perfectly preserved against time, with the saying Verd ori'shya beskar'gam carved along the blade, which also went to Togra, and later Garen Starfall.
