"Forge of War" by Stanley Lau
In addition to the Tolkeinesque, Warhammer adds the setting's defining element - Chaos. Chaos provides the existential threat and underlying theme of the world of Warhammer. Chaos corrupts and destroys.
Chaos is manifest in the Old World through its minions and those it touches. Disease-ridden Skaven infest the sewers under even the greatest cities, animalistic beastmen stalk the dark woods for human prey, and mutants and cultists attest to the power of Chaos to corrupt Man's body and soul.
No fantasy role-playing setting is complete without vikings, and the Chaos-worshipping Norsicans of the Old World are more savage and brutal than any medieval chronicler of Scandinavian pirates could have imagined.
Finally there are the Chaos Warriors. Chaos Warriors are FUCKING METAL incarnate.
