The grimoire card The Aftermath Uldren states he crash landed in the Candor Isles on a sand dune not in a cave in Hellas Basin. Also his crow fix his ship. The next Grimoire card states he was being dragged in Dirt not sand by his captures. Which would mean he and his ship wouldn't be on Mars and on Earth where his captors reside.
