Crystalis[a] is a 1990 action-adventure / role-playing video game produced by SNK for the Nintendo Entertainment System (NES) and later ported to the Game Boy Color in 2000.  The original NES version has been re-released via the SNK 40th Anniversary Collection on Nintendo Switch, PlayStation 4, Windows, and Xbox One.
The game begins with a young magician awakening from the cryogenic sleep he was placed in by the villains of the Great War before nuclear war rained down in the year 1997. Even though he cannot recall his name or who he is or was, he exits the Mezame Shrine and discovers that he may be the key to saving this world from destruction. Aided by four wise sages and a mysterious woman, he rises up against the tyrannical Draygonian Empire to ensure that humanity ultimately does not repeat the Great War.
