|For the purposes of taxation, all unloaded cargo must pass through inspection at Mealvaan's Gate, as must the crews and passengers of docked ships. Established some five hundred years ago by Admiral Mealvaan, the Gate has supported the maritime city-state and her trade since. The arcanists who man it as "assessors" are well versed in sums, and have established the Arcanists' Guild within so as to train newcomers to their art.
A form of arcane art using esoteric calculations, arcanima was developed originally by the people of the south sea isles. After discovering a means of expressing natural phenomena in mathematical terms, they refined formulae into arcane geometries—precise patterns that allowed pracitioners to weave aether into specific magical effect. This, in turn, bore the school of arcanima.
When arcanists crossed the ocean to Limsa Lominsa, they were warmly greeted as lettered men. Of particular note is Ikuku Iku, who came to the maritime city-state roughly five hundred years ago and quickly rose to the position of advisor to Admiral Mealvaan. The arcanist was instrumental in establishing Mealvaan's Gate, and her brethren continue to serve as assessors by tradition. Though the older generations endeavored to train young hopefuls at the gate, the informal relationship of mentor and pupil meant much knowledge was subject to loss. Thus, by order of a concerned Admiral Merlwyb, the arcanists expanded their research facilities, and formally established a guild so that their art might grow with the passing of generations.
