Lucifenia
A vast kingdom called Lucifenia, whose popular name was the "Kingdom of Yellow", was ruled by a tyrannical fourteen year-old princess named Riliane. Under her absolute monarchism, everything was exploited from people and the ones who did not obey her were executed without mercy. Allen, a servant who looked a lot like her, was always beside the princess whom Lucifenia's people called the Daughter of Evil. The princess and the servant were the same age, since the two of them were actually twins who were separated in their early childhood due political causes, with Riliane taking her mother's position as the country's ruler and Allen works in the palace as a servant since he was given up for adoption. The princess's selfishness and jealousy caused a war and many deaths, and their secret clockwork of fate was going to spin madly.

Three Heroes
The Three Heroes are Lucifenia's mightiest champions during the reign of King Arth and Queen Anne. When Arth died due to a peculiar illness, a power struggle started throughout the kingdom. The Three Heroes fought against those who threatened the lives of the children of their deceased king. Unfortunately, the twins were separated in the ensuing chaos, thus Riliane assumed the throne alone after the queen's death.

Resistance
The Resistance, led by Germaine Avadonia, is formed to oppose the rule of Riliane. Poorly equipped but filled with determination, the Resistance has itself based in the Forest of Bewilderment, gaining momentum and waiting for an opportunity to strike.

Lucifenian Allies
At the height of it's power, Lucifenia has secured the aid of many others, though it may not be enough for the troubles that lie ahead.

Elphegort
Elphegort has been enjoying a quiet time of peace, but an unlikely turn of events will threaten that tranquillity. Meanwhile in Eldoh's Forest, an everlasting friendship is formed.

Marlon
Marlon, the island nation of Evillious, has always been shrouded in mystery. Little does everyone realize that its true ruler, the queen dowager Prim Marlon, is waiting, planning something for the whole world to witness.

Freesis Family
Having left Marlon to seek their own fortune in the Bolganio Continent, the Freesis Family unwittingly launched itself into a quest to uncover the truth.
