You have all chosen to follow the Path of the Philosopher. Not for you the warrior Path of the Battlemage, fighter for justice, nor the Path of the Healer, worthy though it may be to heal the sick. Equally you have rejected the Path of the Artificer, the tinkerers, who work on devices and techniques, as well as the Path of the Loremaster, who merely delves and catalogues the knowledge of the past. No, you have decided upon the Path of the Philosopher, the highest calling, the way of true enquiry, where you will probe the realms of higher mathematics, ponder the meaning of truth itself and tease out the deepest secrets of nature and the workings of the world.
The Lord of the Flies, the Muscimancer has studied magics that summon, control and otherwise deal with flies. The Fly Mage is an unwholesome character, also likely to have magics of disease, rot and pestilence up his sleeves.

He can fly, acid vomit, as well as continue to use spells, wield weaponry and command his swarms.
