Fire Emblem: The Cerulean Legion

Fire Emblem: The Cerulean Legion is a ROMhack project that features original characters in a Fire Emblem-based universe.

The Grey Dragon
Legends say that the people of this continent are watched over by a legendary dragon that would judge their souls with the utmost objectivity. However, at some point, the dragon split into two halves, the Light God Deos and the Dark God Sinextra. Sinextra was calculating and rational, but Deos was more brash and impulsive. As a result, Deos felt he had to cleanse the world completely by eradicating all mankind. Sinextra tried to stop him by crafting seven legendary weapons that were given to seven different heroes. With Sinextra's aid, the heroes managed to quell Deos and the two gods stood in the Grey Tower for ages.

Part 1
Centuries after this, the continent has been split into four different kingdoms: Condalia, Taiyo, Manneskin and Kilfer. Suddenly, a small faction of Kilfer becomes independent and, leaded by Eide their new king, declares war on the four kingdoms.

Condalia, one of the kingdoms, hires a small group of mercenaries, leaded by a young man named Sergy, to quell the rebellion and also rescue the princess Alisia, who was kidnapped during an ambush.

Sergy's group soon makes it to Eide's main stronghold and defeats Eide, who is put into a cell and would be judged the day after. That night, the group, alongside Alisia, decides to spend the night to celebrate their victory but, suddenly, a group of monsters appears at the outskirts of the town. After defeating the monsters, a strange woman appears in front of them and warns them that this is only the beginning. In the meantime, Eide is suddenly visited by a man that offers his help at the cost of helping him to "cleanse the world". Eide accepts and escapes from his cell.
