Crazy...
Well this story is probably the first told in the perspective of a goblin. We've seen cultists perspectives, elves, dwarves but always this "smart" bunch (evil or good). This time we've got a goblin perspective (There is also some skaven books Thanquol's and Headtaker). This goblin is smart, it's not a dumb like all his peers. It's evil, cruel but a goblin. True be told, at times it look like some evil looking person but at times some of his actions were goblinesque.
This story is being told by a playwright who, although quite crazy, want to tell the world the tale of the Goblin Warlord Skarsnik. Two other people are investigating goblins and they know there exists some warlord in Eight Peaks but not much is known.
So, this playwright (although in the cover say poet) is telling his tale as warning and we follow the adventures of Skarsnik since birth (they are like mushrooms) until his rise. No, not downfall.
He was smart but small for a goblin, and so the first 200 pages it's basically his first take on life and how he use his wits to learn languages, actions and so on. He also deals with skaven, humans and dwarves fighting each one in turn. Then after the initial intake on the world and being betrayed he goes outside the mountain. As you might know, night goblins are not "night" oriented goblins but goblins that usually spend their entirely life under the mountains. It was also interesting to see his first take and dealings with other hill goblins which although goblins are quite different (bigger in one instance). Then after some take being in confination he rises within goblins/orc society (interesting a dialogue between him and another one where they talk that from time to time some goblins appears that are smarter than the rest - as you know in 40K some orks have a keen to me medicae (well, their kind of medicae)
The remaining part of the tale deals as I said rise and stabbing and backstabbing as he rises. There are some interesting battles by the end that made me wonder what's the reason for it all.
Unfortunately we will never know what will happen because warhammer fantasy it's dead and gone. And all these stories are now crap. Totally bulshit Black Library and Warhammer.
