Effects[edit | edit source]
Once activated, this rune was said to create in place of a doorway a temporary portal between Toril and Annam All-Father's crystal palace Gudheim in Jotunheim. Once closed, this portal could not be re-opened from the Outer Planes.
Components[edit | edit source]
Like most giant runes, it required no material components to cast, though the caster needed to know the giant rune Annam's unblinking eye. The process of shaping this rune could take anywhere from one to six weeks and it needed to be inscribed upon a closed doorway.
