Adrasil was a four-bladed weapon wielded by Atteniel, a female fighting
master of the Mithrodin who protected the Swords of the Ancients from
falling into evil hands in ancient days. The great beast Folkor, servant
of the Dark One, was slain in battle with Adrasil and in later days it
became known as Folkor's Bane. It's blades were forged using the steel
of an ancient Elvish spear. Engraved on them are the names of its
creator, the Baelin slayer Anvari, and the man whom the weapon was made
in honor of, the slain Ettiel, brother to Atteniel.
