Grayswandir is Corwin's sword, also known as the Night Blade. Grayswandir is inscribed with portions of the Pattern of Amber and was forged on the steps of Tir-na Nog'th; this makes it particularly effective against creatures of Chaos. In addition, Grayswandir has one magical property that makes it particularly useful: Corwin can call it by creating a Shadow where he wills it to exist. Unlike a normal blade, Grayswandir can also harm apparitions, and allows Corwin to speak to the shades in Tir-na Nog'th.
