"SPOILER ALERT"mmm, so 3 things I seem to be missing mainly:
1) How to break the chains on the door that's beneath the Temple?
2) How to undo the petrification spell
3) How to get the final weapon upgrade which according to the bard will unlock the blacksmith quest, I think
You must clear the ending first, "spoiler alert" it's not good ending BUT the game not finished yet. You will get pulled back to before you took the last mission, which is the ending, and then then there is some new missions that never appears before
