Ys I: Ancient Ys Vanished
Ys I: Ancient Ys Vanished, also known as Ys: The Vanished Omens  or The Ancient Land of Ys (Japanese title: イース), is a 1987 action role-playing game developed by Nihon Falcom. It is the first installment in the Ys series. Initially developed for the PC-8800 series by Masaya Hashimoto (director, programmer, designer) and Tomoyoshi Miyazaki (scenario writer), the game was soon ported to the Sharp X1, PC-98, FM-7, and MSX2 Japanese computer systems. Set in a land called Esteria, the story centers around the titular civilization called Ys, which had mysteriously vanished 700 years ago with only traces of its existence being kept within the game's six books. When it is prophesied that an impeding darkness would come to threaten Esteria, a young and adventurous warrior named Adol Christin is called forward to collect these six books to aid him in vanquishing the darkness.
