Hermetic Projects (Ars Magica)

You are an Hermetic magus, one of the greatest wielders of magic Mythic Europe has ever seen. You can control the winds with a word, the beasts with a gesture. You can create a forest in a matter of moments, and destroy castles with a thought. No secret of mortal man is safe from your investigation.
So, what do you do with all that power?
Build a covenant inside a volcano, or a tower that touches the sky. Construct enchanted ships to sail any ocean, or even on the clouds. Collect magical beasts from across Mythic Europe and beyond, or become the most deadly opponent in Wizard's War that the Order has ever seen. You could even cheat death itself.
This book describes the spells and enchantments needed to achieve these marvels, using the Hermetic magic taught to every apprentice of the Order of Hermes.
What wonders will you create?
