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.

Because they told us before D2 came out that it would be a soft reboot. That means retcon. Retcon means they [i]change things[/i]. The grimoire was removed to keep people from confusing the old lore with the new. Hence why they called D1 comic book zero. Everyone, including Byf and Myelin, knew this. It seems to have been forgotten. That’s what the folklore line was about. That’s the in game “explanation” for most of the changes. I don’t like it either but the story has been under editing since before D1 came out. This was going to happen and they did warn us. Take every change in stride and adjust to it. It isn’t going away.
