Bolcán Idithe (Booolcan Eeedee) is a small town located approximately 10 leagues south east of Puerto Lejos. The town is built in the partially flooded caldera of a long dead and heavily eroded volcano.
The town is relatively small and unimportant save for two things. Firstly ruins of at least two past civilizations are located here. While no one knows what brought them so far from their base of power in the The Inner Archipelago, the Annwyn Empire had some presence in this island. Several ruins that dot the island are distinctively Annish in style and construction, including the massive Seaward Tower that guards one of the approaches to the inner caldera and the Seaward Keep that looms over the central crater.
Alongside the Annish ruins are still older ones however. These take the form of entrances and labryinths built into the very heart of the rock itself.
While the locals have restored the Annish ruins and use them extensively, they shun the older ruins.
The second reason this settlement is "on the map" is it is the home of a relatively powerful dragonborn sorcerer by the name of Draconis Maximus.
