ChildhoodLeonhardt was born in Hamel, Erebonia.
To protect the world from injustice, Leonhardt diligently practised sword training to join the Bracer Guild.
Over time he befriended fellow Hamel villagers Karin Astray and her brother, Joshua. The feelings he developed for Karin were mutual and Leonhardt swore to protect both her and her brother. Karin would often play the old Erebonian folksong "The Whereabouts of Light" for Leonhardt with Joshua sitting on his lap.
- Main article: Hamel Tragedy
One night in the spring of S.1192, Leonhardt woke up to the screams of fellow villagers and the smell of Hamel ablaze. Jumping out of the window, Leonhardt hurried toward Karin and Joshua, who were corned by one of the invading jaeger drop-outs. He urged Karin and Joshua to run away from the village as far as possible as he tried to hold off the opposing forces.While his opponents did not stand a chance against Leonhardt's excellent skills with a sword, the act of having to actually kill the people who attacked his hometown -- seemingly out of nowhere -- made him sick in the stomach.
When he finally caught up with Karin and Joshua, he found her mortally wounded with a deep cut diagonally across her back. Asking him to look after Joshua, Karin died in his arms.
Leonhardt and Joshua were the only two survivors of the attack, which led to the start of the Hundred Days War.
Upon the realisation that the Erebonian government initiated the attack on Hamel, Leonhardt barged into the Imperial government's office and questioned their motives. Unimpressed, the military officer warned him that they could still easily finish what they started by killing the two remaining inhabitants of Hamel. Together with the heart-broken Joshua, he returned to Hamel. Facing the reality that nothing of his hometown remained, he collapsed to his knees and loudly wondered how this could have happened.
Out of nowhere, Ouroboros Enforcer No. 0 Campanella appeared behind him and asked him whether Leonhardt would like to learn the answer to his questions. Campanella explained the Tragedy was caused by the weakness in humans and projected a vision of the Liber Ark on the ground, clarifying that by using the power of the Aureole mankind managed to create a paradise in the sky. Campanella said his cause is looking for the Aureole in Liberl.
The very moment Campanella asked him to join him in his search, two jaegers appeared out of nowhere and surrounded them. Leaving Joshua in Campanella's care, he killed both mercenaries in a single strike as Campanella welcomed him to Ouroboros. The Grandmaster of Ouroboros informed Anguis No. VII, Arianrhod, that carnage had been born.
Both Leonhardt and Joshua started working as Enforcers for Ouroboros, often in collaboration with Renne. Soon after joining, Anguis No. III, Georg Weissmann, offered to help him mend Joshua's heart. When Joshua finally returned from Weissmann's training, he saw a ruthless killer rather than the enthusiastic boy he once knew.
The next day, Campanella showed up during the tea party with Renne and Joshua on the backside of the tree Leonhardt was resting against. He thanked him for his worked and passed on the Grandmaster's gratitude as well. Insisting there was someone looking forward to meet him, Campanella introduced Leonhardt to Arianrhod, who invited him to a sword duel.
It was a brief duel, with Arianrhod avoiding Leonhardt's attack and planting herself on top of him. As she thrusted her sabre down toward Leonhardt's face, he shielded himself using his own sword. Due to Arianrhod's sheer strength, his sword snapped in two. Arianrhod stood up and informed him that next time they would duel, she would be using her actual weapon: a spear.
While Leonhardt came to the realisation that he still had ample room for growth left, Arianrhod requested him a new sword from her Grandmaster and suggested the Kernviter.
Learning that Joshua failed his mission to assassinate Cassius Bright, Leonhardt lost his patience and demanded an explanation from Georg Weissmann as to why Joshua was sent alone -- on an impossible mission. Weissmann explains that the real purpose of his mission was to get taken in by Cassius and leak information on his whereabouts to Ouroboros as a spy. Frustrated, Leonhardt ran away from his conversation with Weissmann.
When Arianrhod stumbled upon the flustered Leonhardt in a hallway, she invited him to the Celestial Globe so he could receive the Kernviter, his replacement sword, from the Grandmaster directly. Before he accepted the sword, however, Arianrhod stopped him and informed him about the conditions of accepting the sword.
She states the the Grandmaster's Law dictates that Enforcers have total freedom and he thus has the option to accept the sword. The sword, she continues, holds strength that transcends human reason and that by accepting, he will be reborn as carnage, unable to return to his human self.
Concluding that if he cannot return he has to go forward, Leonhardt accepts the Kernviter (魔剣ケルンバイター), forged through Divergent Laws, which is capable of cutting through everything, including the powers of Sept-Terrions.
To initiate the Gospel Plan drafted by the Grandmaster, Leonhardt started working for Colonel Alan Richard of the Royal Army of Liberl's Intelligence Division. Under his alias Lorence Belgar, commander of the Jesters, he fulfilled tasks assigned to him. Richard himself, however, was struggling with his position as Cassius Bright's successor and with how to preserve the peace in Liberl with its position between Erebonia and Calvard. He asked Lorence to work directly under him.
On behalf of Weissmann, who henceforth disguised himself as the archaeologist Professor Alba, Lorence submitted the proposal of an investigation of the Aureole, which would surely grant Richard the power to protect Liberl from any incoming attacks. Professor Alba was invited to discuss the proposal. On his way out, Leonhardt witnessed him manipulating Richard to set the Gospel Plan into motion. The next day, Richard asks Lorence to look for said Aureole.
Leonhardt is a cool yet serious individual who maintains an emotionless mask.In his youth, Leonhardt was a kind individual who maintained a strong belief in justice. He acted like a brother to Joshua and was deeply in love with Karin Astray. However, when the Tragedy of Hamel occurred, Leonhardt became betrayed by his beliefs and the world.
As a result of the corruption and hypocrisies surrounding the event and the turnabout of the Hundred Days War, Leonhardt grew embittered and became angry towards the world and its people (in particular its political and military leaders). Deciding to use this anger against it, he joined Ouroboros.
Despite all that has happened, Leonhardt is still shown to care for Joshua and Karin and is desperately fighting to change the world for them. He heavily despises Weissman for turning Joshua into a weapon, but puts up with him nevertheless. He also highly respects his teacher, Arianrhod.
When Leonhardt under his alias of Lorence reported back to Richard that the Gospel had been stolen by a bracer, he was ordered to get it back. Using Weissmann's manipulative powers to hypnotize Kurt Nardin, Leonhardt started his interrogation. Mindlessly, Kurt stated his name and position as a B-rank bracer and that, indeed, he had been sent by Cassius Bright to take back the Gospel and passed it on again wrapped as a parcel.
The interrogation ended with Weissmann concluding that he would get additional information through Joshua and that Cassius needs to be out of the country for the Gospel Plan to succeed.
Leonhardt, under the guise of Lorence is then seen at multiple points throughout Trails in the Sky FC, conversing with Ouroboros' other puppets or manipulating the situation for his benefit. Mostly he acts as a messenger and even confronts Agate Crosner at one point.
During the Martial Arts Tournament in the Grand Arena in the City of Grancel, Leonhardt ended up fighting against Joshua, alongside Estelle Bright, Olivier Lenheim and Zin Vathek, in the finale. Joshua recognized the fighting style, but did not dare to ask for the identity of Lorence.
Leonhardt, removing his mask for the first time is then last found fighting Estelle and her group when they came to reclaim the Queen and her Castle. After being defeated in battle, Leonhardt informs the group of the remaining possibility of stopping Colonel Richard below and lets slip a mention of Hamel Village, which Queen Alicia recognizes before getting away by jumping off of the balcony.
A Maiden's Resolve
In Trails in the Sky SC, Leonhardt is first seen rudely greeting Campanella in a unknown location near the end of the prologue. Leonhardt tells Campanella that he is late, but Campanella just shrugs it off and tells Leon that he missed him. Leonhardt just responds with sarcasm and asks Campanella if he was responsible for the Jaeger attacks on the Bracer Guilds in Erebonia. Campanella states that he was and that Cassius Bright was magnificent as he countered everything that Campanella threw at him, so much so that he broke the Jaeger group 'Jester'.
Leonhardt laments that even normal men have their limits and states that it couldn't be helped considering their opponent. Campanella asks him if he wanted to trust his luck against Cassius too and Leonhardt replies that he did. But, Cassius is no longer a threat to them now, he then tells Campanella that all of the required members have been assembled including Bleublanc. Campanella then asks about "Him (Joshua Bright)" and states that things are going to be fun from now on. Leonhardt replies that he has since long left the organisation and that he's unlikely to be a threat.
Suddenly, another voice rings out stating that he isn't sure about that. The voice belongs to Weissmann who approaches and greets Campanella and Leonhardt. Weissmann thanks Campanella for delaying Cassius Bright and Campanella responds by mentioning how fun Weissmann's new plan is. Weissmann thanks her for the compliment and mentions how everyone else has their own plans as well. After talking a bit more, Weissman welcomes Campanella to enjoy herself by watching his plan unfold, and Campanella states that she is looking forward to it.
Meeting with Bleublanc
Leonhardt is next seen meeting with Bleublanc who appears on the rooftop of one of Ruan's warehouses. Bleublanc greets his comrade and compliments him on his punctuality. Leonhardt then asks about Bleublanc's report, but Bleublanc wants to savor the scene a bit more. Leonhardt then states that his report will be that "he really likes them" and Bleublanc rants on about Kloe and Olivier.
Sighing, Leonhardt calls Bleublanc hopeless and tells that he is allowed to pursue his hobbies so long as they don't interfere with the plan. Bleublanc tells him not to worry and gives the Gospel to Leonhardt. Pleased, Leonhardt asks how the experiments went and Bleublanc explains that it was about a 90% success, in that it can accurately project for hundreds of selge, but the first two projections were failures and the device worked on the 3rd attempt.
Leonhardt then sums it up that there is some need for concern, but not much since the device functions. Leonhardt then states that he will report it to the professor. Bleublanc marvels at the Gospel and states that even though he knows that it was made by the 'Thirteen Factories,' but wonders how does it work. Leonhardt states that he is not sure since he's not privy to the details of it, but according to the professor, this is just the tip of its miracles. Hearing this, Bleublanc gushes at the prospect of the miracles of 'She Who Rules Above' and wonders what he means by it.
Leonhardt replies that he's not sure, but they will find out after a few more experiments. As he goes to speak more, Leonhardt suddenly senses something and Bleublanc turns in the same direction seeing what Leonhardt had sensed. He then notes on how the cameo will end and Leonhardt draws his sword. The two of them then call the "mouse" out, but are interrupted by the sound of a drunk's voice. Sheathing their weapons, the two tell the mouse that they were lucky and departed the area.
