Myth Drannor

Myth Drannor, formerly known as (the city of) Cormanthor, the City of Songs, or the City of Love was once considered to be the most beautiful and largest of any of the cities in Faerûn. It is one of four old communities of the forest of Cormanthor (the others being the Elven Court, Semberholme and the Tangled Trees).

Today
The city has been in ruins for many years. The city was once protected by a device called a mythal which is one of the most powerful spells in the Forgotten Realms, used to shield Myth Drannor from harm.

Magic
The powerful magic of Myth Drannor still leaks out from the ruin, affecting Cormanthor in several ways, such as the weather being milder than it should be, with cooler summers and warmer winters, and there being far more plant and animal species in Cormanthor than any other woodland of its kind.

There are pockets of Cormanthor that cause magic (spells and effects) to behave in unpredictable ways. According to Elminster these pockets were created as a result of the breakup of the mythal.

History
Cormanthor became known as Myth Drannor after the mythal was raised. It was during this time that Elminster visited the legendary elven city and became the first human to ever set foot in it. Coronal Eltargrim, the elected ruler of Cormanthor at the time, decided to open the elven realm to non-elven races in order to halt the slow decay of his civilization and prevent human armies from forcefully entering the city in the future. The mythal was raised to protect the city once the non-elven races were allowed to go there.

Myth Drannor was later overrun by the armies of three nycaloths after they were inadvertently freed from their prisons in Myth Drannor, despite the elves recruiting dragons as guardians.
