The 15th game in the [[atelier (series)|Atelier]] series and the second in the Dusk trilogy. The Japanese title [i]Escha to Logy no Atelier[/i] parodies the word "eschatology":http://en.wikipedia.org/wiki/Eschatology which is the study of the end of humankind. Unlike many of the previous games, players can choose between a female protagonist named [[Escha Malier]] or a male protagonist named [[Logix Ficsario]] (a.k.a. Logy). The story remains the same overall, but some events and items are exclusive to each character.

Logy reappears in [[Atelier Sophie]], albeit as a completely different character in the Mysterious arc of games. Likewise, Escha appears with him in [[Atelier Firis]], also as a different character.
