Allen Avadonia

"How's the taste, m'lady Riliane?"

Allen Avadonia, The Servant of Evil, is a chamberlain from Lucifenia who serves princess Riliane Lucifen d'Autriche and is the incognito lost twin brother of Riliane.

History
When Allen and Riliane were children, they were chased by a "demon" and they decided to "split" day and night between each other, Rilianne being the day and Allen being the night.

Because of a dispute to decide who would be the kingdom's succesor, Riliane and Allen were separated when they were young. Being considered dead, he was adopted by Leonhart Avadonia, making Germaine Avadonia his foster sister. Allen and Riliane were reunited but Allen kept his identity a secret.

When Leonhart started to smuggle food out of the palace to relieve a famine that struck in Lucifenia, Riliane ordered Allen to kill his stepfather. Leonhart died at the hands of Allen, thus Germaine swore revenge against the princess.

One day, Allen took a trip to Aceid, capital of Elphegort. There he met Michaela singing in town. Allen fell in love with Michaela at first sight. When the "Green Hunting" started, he was one of the few who knew that Michaela was hidden in a well. Allen kept this from Riliane for quite some time until Riliane found out later. She ordered Allen to kill Michaela once and for all and when he finally made up his mind, he found Michaela stabbed by the well and she died in his arms.

When the Lucifenian Revolution started, he refused to abandon his princess. He revealed to Riliane that he was her twin brother and offered to switch clothes with her so that she can escape. Riliane very reluntantly agreed. Allen's plan worked, letting himself be captured while Riliane fled to safety.

Before his execution, Germaine and Kyle Marlon (under the name "Kachess") found out that the "princess" they captured was indeed Allen. Germaine pleaded with him to escape, but Allen refused. Ultimately, he was executed by the guillotine.

Apparently, Allen reincarnated as Irregular, waiting for his "quest" to begin as foretold by the Clockwork Doll.

Daughter of Evil (EC 500)
Allen was mentioned in Daughter of Evil as a servant who shared Riliane's same face.

Servant of Evil (EC 500)
Allen's namesake song, Servant of Evil, describes Allen's life from the day they were separated to his eventual execution. He reveals that he and Riliane were in fact, twins.

Regret Message (EC 501)
Allen was mentioned also in Regret Message. Riliane recounts a legend that Allen once told her: That if a person writes a message inside a bottle and throws it out to sea, that person's wish will come true. Riliane does what the legend says, hoping that if she could be reborn, she will be reunited with her brother someday, in another time.

Twiright Prank (EC 491)
Twiright Prank happens nine years before Daughter of Evil, when Riliane and Allen were children. They were chased by a "demon" who wanted to devour them. They then decided to "split" day and night between them, Riliane being the day and Allen being the night. When the "demon" reached Allen, he felt sorry for the "demon" and offered to share his snack with it. As a thank you, the "demon" tells Allen about the legend of the sea.
