Grand Chase is practically a MMOSPG [Massive Multiplayer Online Story Playing Game] rather than a MMORPG [Massive Multiplayer Online Role Playing Game], mainly because in each dungeon is a storyline including the Grand Chase characters. However, when Ntreev advertises Grand Chase, they refer to it as an MMORPG. The Trial Forest dungeon has no story. After that dungeon, Elesis, Lire, and Arme are in about every storyline. They are first introduced at Trial Tower. The Serdin and Kanavan Kingdoms, the biggest kingdoms on the Bermesiah Continent, coexisted in peace until their lands were slowly overcome by the evil Queen of Darkness, Kaze'aze.
