ASH: Archaic Sealed Heat
"ASH: Archaic Sealed Heat is a 2007 tactical role-playing game co-developed by Mistwalker and Racjin, and published by Nintendo for the Nintendo DS exclusively in Japan. The storyline follows Aisya, princess of Millinear, after her kingdom is burned to ashes by a fire monster on her coronation day. Given the ability to revive the dead as ash-formed bodies, she sets out to investigate the causes behind the disaster. The gameplay combines tactical grid-based movement of 2D characters in a field environment, and traditional turn-based battles when two party units engage represented by CGI models."
