This is a continent full of legends, a world of countless heroes, this is "Salfa" - the country of kings.
Here, the elves fulfill the "Code of Mona" - the elven king spends his life guarding the king of Salfa, and the king spends his life guarding the tree of light "Efilina".
No matter how years pass and time changes, people still live like this. They just need a comfortable home and a comfortable life. But now, people need someone who can continue to protect Efilina and someone who can inherit the throne of Salfa - they know that the country needs a prince.
