A bit of history: there was once a Kingdom on an island known as Esteria (the former prosperous Kingdom of Y's in the last millennium). Virtually the whole world knew about Esteria, because. high-quality silver was mined and smelted from its mines. But when the mines were depleted, they forgot about Esteria. It was to that land that a swordsman, Adol Christin, was nailed by a hurricane - a good fisherman found him, went out, gave money and that and that. Adol was surprised by the generosity of the inhabitants of this land. The fisherman told him that he would find adventure for one place in the city of Minea. In that city, he was told about the Goddesses Y's, who protected the inhabitants from ferocious demons. Their exploits were recorded in 6 books, and if anyone finds them all, he will rule over the Goddesses. The evil wizard Dark Dekt tried to find the books, and no one could resist him. And then, inopportunely, Adol arrived.
So, your task is to find all 6 magic books of Y's. The last, 6th book, is in the hands of the wizard himself. Your only allies are the inhabitants of villages and cities, the rest are demons. In general, full of dangers on the way!
It is impossible not to note the sound quality (which Master System games usually suffered from) - you immediately plunge into the atmosphere of the game.
