I found this note from The First Door under the carpet in his hiding place. It isn't his next quest, but it is something new coming soon:
Something
new is coming, something different to what has gone before.
This something is in between, after and before, the new based on the old and what has yet to come.
Soon a different style of quest will begin. Soon things will begin to move again.
But yet, this is not the full story; it is not finishing what once was begun. Only time will tell what will come after. Those who have helped shape my past will need to return to shape my future.
Soon everyone will be able to take one more step; soon a box will need to be opened for the truth to be revealed once more.
Solve the puzzles and maybe one quest can lead to another...
