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.
