Yes, I am Thubyrgeim. Greetings, and welcome to the Arcanists' Guild. As Murie has doubtlessly explained, I am serving as acting guildmaster until our wayward leader deigns to return. I assume our capable receptionist also spoke of our art's origins?
Allow me, then, to expound upon its nature. Arcanima taps into the living energies of aether. The evidence of this is represented most aptly, perhaps, by our ability to manifest the arcane entity Carbuncle, and the manner of magic which this aetherial ally employs at our command.
The core of the discipline, however, is found in the pursuit of definitive solutions to any potential quandary. Even on the field of battle─nay, especially on the field of battle─this principle takes precedence.
If one wishes to make certain the question of victory, then one must apply the most effective strategy. An arcanist is measured by his ability to calmly analyze a situation from moment to moment, and respond with the most appropriate spells at hand.
The study of arcanima will test your mental faculties to the point of perplexity. Are you prepared to reason your way through predicament after predicament?
