Ice

Ice was a Valyrian steel greatsword and an heirloom of House Stark. It was used both in war and on ceremonial occasions by the Lord of Winterfell. Ice had been in the possession of House Stark for generations and was kept in a special scabbard crafted from the pelt of a wolf.

Ice's service to House Stark ended when she was dishonorably used to behead Lord Eddard Stark for supposed treason on the orders of King Joffrey Baratheon.
