The Cube of Rubik

you've been an adventurer for a while now, taking quests from the Guild and the odd job. You've heard rumors of a mage's tower that was home to a renowned mage. Now it's been long abandoned and apparently empty. It's located in a verdant valley filled with forests and meadows. You find it after weeks of travel. Other than the dust and cobwebs there's seems to be nothing
