Juan Carlos the Sun Watcher, the legitimate son of Duke Rubio the Sun Watcher of Duke Margaret, and also the youngest son, has just passed the selection of the Flame Sun Knight Order, becoming a formal Flame Sun Knight, which is quite remarkable for a noble scion.
However, this also caused Duke Rubio the Sun Watcher of Duke Margaret to feel troubled; on one hand, the Duke is happy and proud of his youngest son's excellence, yet on the other hand, he is troubled by it.
Because he has more than one son, his legitimate eldest son Felipe is twenty-nine this year, has accumulated considerable strength within the Kingdom, and has a group of his own supporters. The emergence of an outstanding youngest son is not really good news for inheritance.
