It was one of those days... so I am a little late with this, but wow... that is an interesting model.

With only a few days to go before Soul Wars is available to pre-order (seriously – we can hardly contain ourselves), we’re ready to reveal just who is leading this deathly assault on the Mortal Realms – the shadowy Mortatch of Grief who commands the Nighthaunt legions:
Behold, in all her glory – Lady Olynder, Mortarch of Grief!
Nagash is a being of exceptional power, but cannot be everywhere at once, and apportions his vast energies between the Mortarchs. Olynder is the most recently chosen of these dark lieutenants, gathering the previously disparate forces of the Nighthaunt into a terrifying spectral legion who fight at the spear tip of Nagash’s latest assault on the Mortal Realms.
In life, Olynder was a plotter and schemer who showed false remorse to improve her standing – now, in death, she is the possessor of a misery so deep and black it projects from her in vast, deadly waves. For most, to face her in battle is to lose hope and accept the inevitability of death – while those few with the will to stand before her are quickly obliterated by her deathly magics, or torn apart by spectral attendants.
We’ll be seeing more of Lady Olynder – and her Nighthaunt armies – soon, with Soul Wars being the tip of the (terrifying, definitely haunted) iceberg…
With the Mortarch of Grief revealed, only one named Nighthaunt hero remains unseen – if you fancy indulging in some wild speculation
