Port Aren is a city built on the island of Crandor after you finish Dragon Slayer. Until after you finish the quest Fountain of Youth, you cannot use any of the public facilities such as the bank, as all of the inhabitants speak an odd language called Crandish. After completing the quest, you are given a Book O'Crandish with which to translate. The city is connected with the mainland by the Tunnel of Aren, a "subway" of sorts leading to Rimmington.
