Halo of Thorns - Drew Bryenton

This is a story of an Evil lord. But it's not told by the grinning, lantern-jawed heroes or simpering sorceresses who have been trying to kill him for three hundred years.

It is the story of Kuhal Moer, uneducated son of a drunken warlord, and of how he came to be the single most feared entity this side of Death himself. And when the hero of your saga is a cynical and slightly unhinged young necromancer, you can bet that the villains are going to be something else entirely...

Kuhal Moer wields powers that bend gods into trembling wrecks as he summons towering beasts from the mud of the battlefield composed of the corpses of the slain. Ride with the Drakken in the icy skies above vast war keels hewn from the mountains themselves, floating stone war cities bristling with canons. Witness city-levelling magical battles that tear the very fabric of the universe asunder.

… and the Nameless ones. Well, what can be said of them except that they make the Cenobites from Hellraiser look like the Teletubbies in comparison.
