Age of Sigmar Nighthaunt Myrmourn Banshees

The Myrmourn banshees have a diabolical hunger, for they feast solely upon magic. No enemy spell is safe from the ravenous spirits, and they haunt the Mortal Realms in search of arcane energies to consume. Myrmourn Banshees are drawn to magic as carrion are drawn to the dead, and such is their bitterness toward life that any mortal creature in their way is likely to receive a swift jab from their cursed chill daggers.
