The Sword of Etheria[a] is an action role-playing game developed and published by Konami Computer Entertainment Tokyo.

[2] The Sword of Etheria is set in an alternate world where humans, gods, and spiritual beings known as "Katenas" coexist.

The game shifts forward fifteen years later to Fiel ("Feel" in the Japanese version), a boy who lived with his younger sister, Dorothy, and their cat, Toto.

The Sword of Etheria is presented in a third-person perspective, with players controlling the actions of the main character, Fiel, such as interaction with objects and people.

Enemies can be launched into the air to perform juggle combos, and players can accept aid from their partners for additional hits.

When the gauge is full, the player will have the ability to perform a powerful "deathblow" attack, combining the party's force to deal extensive damage to the enemies.

At its highest level, a filled gauge displays the text "Over Zenith," signifying that the strongest deathblow can be performed.

The director and producer, Junichi Murakami, directed Castlevania: Aria of Sorrow, while the composer, Michiru Yamane, worked on the music.

The soundtrack features an arranged version of the song Polovtsian Dances, played during the opening sequence of the game, performed by Martha Matsuda.

[7] PALGN's Jeremy Jastrzab commended the use of the game's music as a stylish and the unconventional presentation but made a note on the poor graphics environments, saying that players are usually surrounded by either dull corridors or barren landscapes.
