The Russian Czar Peter the Great commissions Jonathan Green, an English traveller, to map the Far East territories of the Russian Empire. Green sets off on yet another long journey, full of unbelievable adventures, which eventually leads him to China. On his way, the famous cartographer makes breath-taking discoveries, meets mysterious creatures, Chinese princesses, deadly masters of oriental martial arts, and even Lun Van, the King of Dragons, himself. What could be more perilous than looking into the eyes of Viy? Only meeting him again… What will prevail this time — the unflinching scepticism of the scientist or ancient black magic, which has already gained influence over the Far East Lands?

The realm of magic is being threatened by the realm of logic, so Carolinus, the green wizard decides to shield it for all time. Ommedon, the evil red wizard, stands in his way. Carolinus then calls for a quest that is to be led by a man named Peter Dickinson, who is the first man of both the realms of science and magic. It is Peters job to defeat Ommedon.
