She is the Mourning Bride, the Unrequited Queen, the Veiled Lady and the Mortarch of Grief. She is despair made manifest, gloom given form. She is Lady Olynder, and in her are bound all the sorrows and anguishes of the realms.
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.
