Sorry my bad I missed that one. You can get there by going east from the dead dragon at Grand Altar of Dragon Communion. To reach this location, you will have to go through Dragon's Pit dungeon. I t will take you some time to get here. Let me know if you have any doubts.
@@HeyGameRekt yeah I realized you could ride over the dragon at the alter shortly after saying this. The first time I got there I just automatically assumed you couldn't go over the dragon and that there was another way to get to that area. That is how many other games would have done it lol
