You were a member of the royal family, young or already an adult. By order of Queen Ruby, if any member of the royal family went further than the castle, he always had to have a special personal guard with him.

And so you walk down the corridor to the room with the guards. Once inside, you see only one free companion, a young and small female. Her name was Ruby, just like the queen's.

Ruby sits and diligently cleans her helmet from the remnants of blood. She didn't look at you and hurriedly said wait a minute! I'm done and ready to follow you!
