Mundus' Journal is a book written by the mage Mundus, and can be found on a table in his quarters in the High Hall Mines.

The Earth, the power of the Earth! I know it all, I master it all! Now that I've finally finished building my rune portal, I can use it to summon any kind of creature - assuming I find the adequate rune. And, as luck would have it, Father was in possession of a Troll rune. How helpful! Now these peasants from High Hall will finally learn to respect me!
