There once existed the Realm of Anthronia, where battles were fought for years on the dustplains of Scorvor between men and wolves. Eventually, Lord Anthross got thirsty, and asked his slave to bring him some ale. The slave took too long setting about this task, so Lord Anthross had him beheaded, and called for his new slave. The new slave hastily brought Lord Anthross his ale, but switched the contents of his tankard for a new kind of special, black, sugary ale (Coca Cola). "By Thrantor, what be this ale?" asked Lord Anthross, when he first tasted it. His new slave replied "Master, that be no ale. That be... Devillion's Brewnog!"
Needless to say, it was an instant hit, and Lord Anthross commissioned gallons of this new ale to feed his fatigued armies, who thenceforth got stronger, and won their epic battles, giving new life to his empire.
