where is the Storm Star located

[patch]

hey guys I can not remember for the life of me where I read about the magic morning star "storm star" it was made by the Netheril. If anyone remembers please let me know. I am doing a Norse thyme and it would be a great idea for a hammer to the god Thor. Thanks for your time.
