Creating a New Silhouette Knight
The king wanted to figure out what's Ernesti agenda, so the king summoned Ernesti and Ernesti's grandfather. The king tried to learned Ernesti agenda by testing him by rewarding Ernesti for his success on defeating the Behemoth. Ernesti's granfather Lauri pointed out to the king that Ernesti is still a child and that he does not need a reward. The king insist child or not he will not fail to reward someone who have defeated the Behemoth. So the king plainly ask Ernesti "what do you want". Ernesti was surprised by the king's offer and was speculating that the king is not doing this out of the kindness of his heart, Ernesti assumed the king was testing him. Ernesti bickers upon himself whether or not he should or shouldn't ask for a reward and that if he were to ask what would he ask for? He question himself. Ernesti kept on thinking, he could just ask for the latest model of Silhouette Knight. Ernesti said "no" to himself and told himself that this is the chance of a lifetime. So Ernesti said to himself that he need to ask something difficult and that he will never get another chance to get. Ernesti finally asked for something only the king could get him which is knowledge, and it's mostly knowledge that Ernesti craved for, on how to create the heart of the Silhouette Knight the Ether Reactor. The king asked Ernesti his reasons for doing so. Ernesti answered that beacuse its his 'hobby'. Surprised, the king laughed and agreed in one condition: create a Silhouette Knight.
Hence, Ernesti started working with the dwarves to create a new Silhouette Knight. Ernesti used the Trandorkis, which she glady allowed as a test pilot. Along with the help of Edgar, Diterich and the twins, Ernesti experimented his ideas including the Silhouette Gear into development. Unaware, enemies of unknown organization plans to steal his creations.
Several days after the Casadesus Incident, the King Ambrosius ordered the summons of the students who were involved in the development of the Telestale to Schrieber Castle. (PlsInsertMissingStory).
