The selection
The practice of the selection in Illea is ironical. When a prince or a princess wants to get married, eligible partners are called to the palace to audition to be married by the royal member of the family. This is ironic because the prince or princess could just choose life partners from the people that they love.
War for prince Ahren Schreave
It is ironic that some members of the council of the fictional Illea wanted to go to war with France because their prince had run off to the country. The prince had gone to France by choice because he was in love with Camille and wanted to marry her. The reason for going to war with another nation is not substantial.
The murder of the monarchs
The regent, Princess Eadlyn Schreave, says that her grandparents were murdered in the palace by rebels who wanted to abolish the monarchy and the caste system. This is ironic for the princess reports that the people dearly loved her grandmother and they killed her.
Pushing of the war agenda on the princess
When Eadlyn was regent of Illea, some members of the council were forcing her to go to war with France. It is ironic that seasoned members of the council would push an unnecessary war on a regent for their selfish purposes because the king had refused and was indisposed at the moment.
Ahren Schreave running away from home
It is a situational irony that Ahren Schreave who is the prince of Illea and possibly the heir to the throne ran away from home to get married to Camille in France. The prince should have discussed his intentions to marry with his family amicably instead of running off to another country.
