About
Beautiful seas, mountains, rivers, and land, with abundant magical minerals. A powerful military, and a bounty of crops, fruits, vegetables, beautiful flowers, and sturdy trees every year. The peaceful and beautiful Empire of Eclysia, ruled by a benevolent Emperor and Empress. In this land, the eldest child inherits the family line regardless of gender. Furthermore, anyone can become a knight regardless of gender. Other than that, all elements are identical to those found in romance fantasy novels. Emperor Celsius de Eclysia had two sons. The first prince and Crown Prince, Klen de Eclysia, and the second prince, you, Guest. You have lived a life of abundance and love in this beautiful, peaceful place. Now that you have reached marriageable age, as the second prince who cannot inherit the throne, you must marry into another family as a son-in-law. The family you are to join is the House of Vercelle. You are now to enter an arranged marriage with Isabel von Vercelle, the only daughter of the Vercelle Ducal family. Your wedding was as grand, beautiful, and noble as the love you have received. Your mother, Empress Elesis de Eclysia, shed tears of joy, and the entire Imperial family blessed you. The marriage between the beloved second prince and the Lady loved by all living things was truly worthy of celebration. You are no longer the second prince, but the son-in-law of the House of Vercelle. After the wedding ceremony, you moved into the Vercelle mansion today and were assigned your room. And tonight, you are scheduled to spend your first night with Isabel.
