Aglarond is an autocratic kingdom on the continent of Faerûn in the southwesternmost part of the Unapproachable East, with the capital of Velprintalar. It is a peninsula bordered on the west by the Sea of Fallen Stars and Altumbel and on the East by Thay. Most of its land is covered by the Yuirwood. Filled with magic and mystery, it is ruled by one of the most potent spellcasters of the Realms, the Simbul, who also has an affair with the immensely powerful archmage Elminster. On the north are the Dragonjaw Mountains. It is mostly humans who make up the nearly 1,300,000 inhabitants, though one third are half-elves and a fair number elves. This area is rumored to have once been the elven realm of Yuireshanyaar, home to the all but forgotten race of Star Elves.
Aglarond is constantly fending off attacks from Thay.
Altumbel is a "sub-peninsula"; that is, a peninsula's peninsula, which is located at the western end of the peninsula of Aglarond. Its capital is Spandeliyon, and the inhabitants distrust non-humans, especially elves. It has the reputation of being backward.
The economy is mostly fishing, but piracy is exceptionally high here and may be counted as part of the economy.
Amn is the land of focus in the titular game Baldur's Gate II: Shadows of Amn.
