"Draconus. A lovely world."
"If by 'lovely' you mean freezing, dangerous and bleak then yes I have to agree"
—Alin Quell and Tristan Fett
Draconus was a planet in the Mandalore Sector. It was one of the very few sources of Kyber crystals not controlled by Jedi. For this reason Mandalore the Dark allied with it before the Jedi could step in.
In 3478 BBY the planets goverment allied with Mandalore when they found Kybercrystal mines.
