Welcome to Warhammer. Sound the trumpets and beat loud the drums of war, for the weighty tome you hold in your hands is your key to entering a dark and bloody land. It is a world of Daemons and sorcery, a brutal era of warfare and conquest. Warhammer, the game of fantasy battles, brings all the action onto your tabletop. You command armies of miniatures in a game that promises bold manoeuvre, daring riposte and untold slaughter.  The game of Warhammer makes you the general of an army of fantasy miniatures. Regiments of resplendent High Elves, the ragged hordes of ravenous ratmen known as Skaven, the Undead legions of the Vampire Counts or any of the other dozen army types, march, manoeuvre and charge into the fray on your orders. At your command, hails of arrows and eldritch bolts of magic are unleashed upon the foe. But it is in the brutal close quarters of combat that most battles must be won, by stalwart troops and legendary heroes.
