Thought we may as well follow on with these as the characters will still be fresh in our minds 
Here is the current list:
Ancient Bone Dragon - 370pts
For many years the dragons have travelled to the Plains of Bones when they knew their lives were nearing the end. At the centre of this place of death, carcasses the size of hills can be found, the remains of the fathers of the drakes. Only the acolytes of Nagash have the power to summon these giants back once more, but to do so gives them a servant that is nigh on indestructible.

Bones of the Earth
Muscles and skin have long wasted away on these creatures, but the bones they leave behind are held together by a magic so strong that they are almost impossible to break.
The Dragon has a 3+ Scaly Skin save
Father of the Dragons
These beasts are the ancestors of the lesser drakes, and they are a stark reminder that they are not as immortal as some would believe. The sight of the long distant kin used in such a way can deter even the most determined of dragons
An Ancient Dragon causes fear in all other dragons with the exception of Dragons who are ItP.
Violated
To some extent the dragon's spirit clings to its bones, enraged beyond belief at the desecration of its long dead body. At times it grows strong enough to manifest with a roar of pure hate and terror.
One use only. This attack can only be used in the shooting phase, and may be used when the dragon is in combat. Roll 1D6+3. Any units within this range must take an immediate Panic check at -2 Ld. Violated has no effect on units which are ItP.
Dragon Shade - 300pts
Not content with summon the bodies of the ancient dragons, Nagash sought supremacy over their noble spirits as well. In time the most devious of his magics managed to corrupt their souls, chaining them to his command forever

Ethereal
Large Target
Cradle of Shadows
Whilst its ethereal form does not allow any to ride this dangerous creature, its magical nature allows it to takes it master inside itself, delivering them safely to wherever they are commanded
This rule overrides the normal ethereal rule and allows corporeal characters to use the Dragon Shades as mount if the option is available to them.
Essence of Decay
The merest touch from this dragon leeches vitality from its victims. Those who are not slain outright by its claws find themselves ageing rapidly unto decay as the years rush forth to claim them and even their equipment.
At the end of every combat phase every enemy model in BtB contact with the Dragon Shade must take a toughness test. If failed the model suffers a wound, no armour saves allowed.
Will of the Master
Dragons are noble creatures, and though dominated by another's will, an Inkling of their former personality shines through.
If the rider is killed, then the dragon starts is slain outright, no saves are possible against this.
Fellbeast - 185pts
In the air above Nagashizzar, many terrible creatures swirl and glide around the spires and towers of the fortress. They are an unholy amalgamation of animals, twisted by the warpstone they are exposed to on that fell peak. The opposite of the noble Hippogryphs, they often have a sinuous snake-like body, with the wings of a bat and the head and front limbs of a dragon. However, whatever there varied may be appearance, there is no doubt that these creatures are deadly, capable of ripping a man in half with their claws, or devouring a horse in a bite.

Greater Carrion - 30pts
The Land of the Dead lies to the south of Nagashizzar, and in its great expanse the armies of the Tomb Kings can often be seen. Like giant fleshless birds circling above, the Carrion are hideous creatures attracted to the scent of blood and battle. Nagash makes use of these creatures in his forces, and bestows the Carrion upon his generals. this is a great boon, letting them soar above the enemy, and as a steed the Carrion are as vicious as any creature in the desert lands.

Arabian Warsteed Hero Mount +12pts / Lord Mount +18pts
In the deserts of Araby, to the south of the Land of the dead, the armies of the Sultans ride to war on great Warsteeds, large noble beasts with a fiery temperament. Nagash breeds many of these spirited horses for use in his armies, and those living followers of his will often be seen riding to battle atop one of them, ready to charge down his enemies in a mass of Man and Horse all but impossible to stop.
M 8 / WS 3 / BS 0 / S 3 / T 3 / W 1 / I 3 A 1 / Ld 5
Dead Horse - Hero Mount +12pts / Lord Mount +18pts
Not content with living steeds, the Great Necromancer and his generals choose the fittest, most bloodthirsty Arabian warsteeds and flay the flesh from their bones with their dark powers. Their lively spirit remains bound to the bones now capable of carrying a man or undead tirelessly over league after league no matter what the terrain. These Skeletal Steeds are given to Nagash's elite, to spurn them on ever faster to greater acts of service to their lord.
