Ys: The Vanished Omens

Ys I, originally known as Ys and titled on-screen Ancient Ys Vanished: Omen, 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-88 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.
