Looking for the female protagonist who retired from the world at the beginning and rescued the male protagonist who was sacrificed.

He wanted to find two novels:
1. The female protagonist is a general or something. Because the people she cares about died in battle, she sealed her power and lived in seclusion. Later, the female protagonist's brother went to find her and returned. On the way, he sensed a silent cry for help and saved the man who was sacrificed. The man was penetrated and locked by the black iron chain. The female protagonist recovered her power and released the chain. The male and female protagonists would go crazy on the night of the full moon.
2. The female protagonist seemed to be from the royal family. Her mother came from a mysterious force that surpassed the royal families of various countries and lived on an island. The female protagonist's mother asked the female protagonist to return and not marry outside. The female protagonist's cousin also came. Later, the female protagonist, her lover, and her cousin gathered an army to break into the island. There were many traps on the island, and everyone discovered the secret of the island. Because the island did not allow intermarriage with the outside world in order to maintain the bloodline, many years later, almost all the people on the island married close relatives and gave birth to many deformed children. The island owner killed many newborn children to avoid panic.
