Arcturus: The Curse and Loss of Divinity (악튜러스) is a Korean developed PC role-playing game created by both Sonnori and Gravity. The title was published in South Korea by Wizard Soft on December 12, 2000 and is often considered a classic that helped lay the ground work for Gravity's Ragnarok Online, a very popular MMO that shared the same graphics engine as Arcturus. A few years later, Nihon Falcom released Arcturus in Japan on June 30, 2003.
After Arcturus was released in South Korea in 2000, there were plans to potentially release the game in the United States. An official English demo of Arcturus was created in 2001 which was uploaded to a few tech sites, such as Softpedia, and is believed to have been used to demonstrate the game to western publishers at E3 2001. However, an official localization of the full game never materialized. A fan project to translate the Japanese version of Arcturus was started in the early aughts by Mirror Moon although it was eventually put on hold in 2008 and was never finished. Eventually a user named Helly released an English patch for the Japanese DVD edition of the game in 2017.
Arcturus takes place in the year 738 on a continent ruled by three powers: The Kingdom of Varensia, The Republic of the Seven Lords and The Ashirian Empire. The story is separated into two scenarios that focus on groups of characters from two of the different regions on the continent.
The first is a quite boy named Sizz, who is often mistaken to be a girl, and his neighbor Maria, a bratty tomboy that is often mistaken to be a boy. They both live in the small town of Tranquilee inside the Kingdom of Varensia. Sizz's mother passed away when he was young and now his father, a once famous hero, is an alcoholic that often verbally berates his son. After Sizz's father sells the land where his mother's grave is located to the Church, he finally decides to run away with Maria to the big city. However, they are soon mistaken to be a pair of thieves known as the Aarseth sisters and end up killing an officer in order to escape from the law. After running away from the authorities they are rescued by a magic user named Eispein who teaches them how to defend themselves and tells them about the mysterious Dallant stones. After Eispein leaves Sizz and Maria for unknown reasons, Maria greedily decides they should search for the Dallants in order to sell them.
The other scenario follows a playboy noble named Elluard that lives in Dome, the capital of the Republic. He is given a special mission by his uncle Albrechts, the prime minister of the Republic, who wants Elluard to search the continent for the Dallants. The Dallants are magical stones that grant great power to their owner and Albrechts wants to collect them in order to keep them out of the hands of the Republic's enemies. Little does Elluard known, the Republic is actually secretly ruled by a powerful group of hooded old men and Albrechts is merely their public-facing puppet who is trying to break free of their control by obtaining the Dallants. Eventually these two groups join forces, along with other characters, to search for the Dallants together which leads to them uncovering the truth behind the stones.
- Many Korean fans speculate that Arcturus heavily influenced the direction Falcom took with 2004's The Legend of Heroes: Trails in the Sky. Both games have a similar presentation, containing 2D character sprites on 3D backgrounds, and both emphasis complex storytelling over gameplay mechanics. There were even rumors that Falcom may have licensed Arcturus's game engine to use on their own titles but this does not seem to be the case.
- The horror game White Day has several collectable game packages hidden inside the school it takes place in. All the games are titles previously developed by Sonnori including two versions of Arcturus, the regular and limited editions of the game.
- The themes of Arcturus's story were influenced in part by death and black metal music with the game's title being a direct reference to the Norwegian band Arcturus. The game's subtitle, "The Curse and Loss of Divinity," is also very similar to the song "The Loss and Curse of Reverence" by the black metal band Emperor.
