In the deepest part of the forest known to those who have survived its depths as the Razor Webs, a goblin was born, more spiteful and strong than any living goblin before him. But more, this stubborn and vicious creature was filled with undying rage against all creatures, tempered only so far as those of his own kind and those he could use for his own needs.
His bullying, nasty persona and his strong limbs rapidly gave him a position of power in his tribe and soon he was leading his followers into battle against the other disparate goblin factions within the woods, quickly assassinating any and all rival contenders for total leadership. In only one year and four days, the goblin had defeated every greenskin within the woods who might have opposed him and gathered all others under his dark banner.
Looking out from the branches of the tallest treetop of the forest at the greater valley of the Border Princes, the newly crowned Goblin King glared in undisguised enmity and quivering rage at those races that dared to draw breath within his sight.
He loathed them. He wanted to destroy them.
And now he had the forces to do it.
Marshaling the goblin commanders and shamans in his sway, he called to the spider lords to gather their swarms. Death was coming to the Border Princes until all but the goblins lay dead!
The Goblin King
The Rockstone Helm (Magic Armour)
The helm protects its wearer, granting a 5+ Armour Save and a 4+ Ward Save
Designer's Note: The rules for the Goblin King are fairly legal with one minor exception. This guy is tough and as such he uses the base stats and points value of an Orc Warboss (he's just on a smaller base). The magical equipment is stuff out of the Warhammer rulebook.
If you're interested in the model, he's the Goblin King from Avatar.
