Ghost blood

Five centuries ago, people lived in fortresses and wore iron armor. There were troubled times, where terror and chaos reigned around. They write that then people fought with dragons and dishonesty on equal terms. To equalize the forces, people used magic. The ancient scriptures have long been lost and only you have the only book left that tells where such potions were created for the possession of superhuman strength. Our hero deciphered the book and went in search of mysterious potions. Your path begins from the very place that is indicated in the book. Beware of the ancient evil, because it still wanders not far from those places where there are particles of magic.
