From Destinypedia, the Destiny wiki
Athabasca (also known as the Candor Isles) is a location on Mars. Prince Uldren came to that region twice, once after he had located the Black Garden and after the Battle of Saturn, where he crashed his ship. His Crows met him there.
- Athabasca Valles is a on Mars. Interestingly, all of the Candor locations are nowhere near Athabasca.
- Strangely, while Uldren Sov's ship was mentioned to have crashed here, it was then found in Hellas Basin. This may be a developer oversight/in-game error.
