Aranthíl is a fortified town centred on the eponymous mage tower. It originated as an important Castanorian fort that held the highest river crossing of the Luna River. During the War of the Sorcerer-King the fort was occupied by the League of Free Realms and became the first place where the elven sages, such as Garion the Wise, taught elven magic to humans.
History
It was in Aranthíl that the Empire of Anbennar was formed during the Grand Summit of Aranthíl in 1221 where the mages enforced peace amongst the warlords of the Interregnum. It quickly became the home of the imperial court for the fledgling empire until the Wars of Rule when the court moved to Anbenncóst. Aranthíl remained in magical hands, becoming the bastion of the Magisterium's sphere of influence in the east. It also served as an an external campus for Anbenncóst's Imperial Academy, allowing for more powerful magical spells to be trained without endangering the much more urban and populated environs of city.
During the rise of the Ravelian faith, Aranthíl came under control of the Ravelian Rectorate and became its capital. Aranthil and the River Luna as a whole would be a bastion of urban Ravelianism.
