Hello, I found a solution that might get you out of this mess. The trick is to go back to a previous save, as there's a moment in history that hasn't been completed.
1: Open the Save Folder file
2: Find the previous save before you entered Voidal Chasm
3: You rename the file Game_1 (or 2 or 3 depending on your game)
4: Restart the game and go back to talk to Erin in the palace to go back into the story.
There you go, I hope this helps. Sorry, my English is very bad.
Good game
