At the age of 9, Ernesti started studying at Knight Runners Academy as an Elementary Student along with his friends Adeltrud and Archid. While in class Ernesti (PlsInsertMissingStory). Ernesti figured out if he can't change himself, he could change other things and that he will just have to create Silhouette Knight unit of his own then he goes on monologuing about customization of the Silhouette Knight. Ernesti figured if he needs to know how to create a Silhouette Knight, he needs to get out of the Magical Fundamentals Class. (PlsInsertMissingStory). Ernesti and his friends help out Batson, by blasting Batson in the air to reach the bullying thieves. (PlsInsertMissingStory).

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 in defeating the Behemoth. Ernesti's grandfather Lauri pointed out to the king that Ernesti is still a child and that he does not need a reward. The king insists child or not he will not fail to reward someone who has defeated the Behemoth. So the king plainly asks 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 questions 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 needs 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 because it is his 'hobby'. Surprised, the king laughed and agreed on 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 gladly 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). King Ambrosius ordered the creation of a new Knightly Order under the command of Ernesti Echevalier, to which all the students were surprised. Lastly, King Ambrosius was considering the new Knightly Order name, to which he (missingpart) so King Ambrosius named the new Knightly Order as "The Order Of The Silver Phoenix"
