The city's streets were constructed under the direction of the Magician's Guild to focus magical energy for the city's defense. Indeed, the walls of the city are said to be sentient. The walls appear comfortingly secure from the inside and hostile from the outside. Many would-be conquerors have been beaten back by the walls of Toran.
The city was razed when the Darklords invaded Sommerlund in MS 5050. Zagarna directed a horde of kraan and zlanbeast against Toran. The walls could not defend against these flying terrors as they dropped fire from above. The airborne attack was accompanied by a naval strike.
