Mordred’s Journal contains a clue of where the Lost Princess is. It says, “I have found a nearby moon with much activity that I believe to be alien life! I have found that animal waster makes decent fuel, and there is just enough manure in Arturus to bring my flying craft to the moon. The coordinates are 56,52.”
How to Get the Missing Page from Mordred’s Journal
When you’re back standing next to the fountain, walk left to Mordred’s Museum and go inside. Go up onto the top floor and then click underneath the bed. You’ll find a missing page from Mordred’s Journal.
