Dark Angel of the Shadowfell

The Birdcage, a collosus forged from the deepest darkness and the souls swallowed by it. It serves the Raven Queen, capturing soul of the living and the dead that catch her interest and ire alike. This creature towers above battlements and can easily smash its way through walls if it needed to, hovever the army of shadows at its feet often sack all form of opposition long before it closes in.

Those it captures, become brightly colored spirits in the shape of birds, imprisoned in the cage-like halo around its head, constantly flitting about and crying for freedom that will never come. It is at its most merciful when it simply kills you instead of dragging you to face its dread mistress. It is without mercy, compassion, and cannot be reasoned with. Once on the hunt, it will only give pause at high noon before it continues to track it's quarry down.
