This is a skip you can do before talking with Aurelia.

Quick Roll to Volcanic Caverns: There is a corner in the beach that doesn't stop you from swimming up. You can use that corner to go very high, angle yourself to the mountains, save and then use climbing storage to roll all the way to the Volcanic Caverns. I don't show it in the video, but you can do a safe float down by saving near the exit, then dying with climbing storage in another save and then reload into the save with the save near the exit. This will allow you to walk around with the float state that you will lose the moment you run into any momentum. Now you can enter the exit without needing to enter to the dungeon.

Save Warp: If you leave the end cave and then exit to the main menu while the game is loading, it will be interrupted. You will see a black screen, but you are on the main menu. You will want to tap on the load game option and then tap the check mark to load the auto save that the game selected first. You will have wrong warped to the top of the end cave with the Felforge Hammer. This allows you to completely skip the Volcanic Caverns, including the dragon fight.
