I hope we can build this up with time as a guide to make sense of everything.
Here is my first addition to the section: Character Profiles
Name: Arane A.E. (Anguis d’Infâmes)
Real Name: Tela Serus
Species: Lizard
Likes: Showing off, blood, fighting, teasing Xia
Hates: Justice, authority (especially the Godmother, Overlord and Death Lord)
Biography: Arane is the second Lizard to be created, after Terra Stelio, and is therefore the second Guardian of the Chaos Realm. As the Originals were failed experiments, the next creations had more restrictions on them. While Lebenden was given too many emotions as opposed to Risenden’s lack of, Tela Serus was given finite power and put on a very tight leash unlike Terra Stelio who was given infinite power and freedom. The reason for creating secondary Guardians is because of the failure of the Original ones. The secondary Guardians are also closely associated with the Chaos universe and can be seen as the primary Guardians of it (while the Originals, obviously, were Guardians of the Original universe).
Arane is forced to follow orders by force through the aforementioned ‘tight leash’ aka the invisible red chain-strings of fate/Godmother. While in his contract with Xia he was bound to her via hands to signify their (slight) equality in the deal, the dominance is asserted through him being bound by the neck to the Godmother. Over the many millennia, Arane has worked around the system and mostly does what he wants within boundaries which he prods but never oversteps. The Godmother and the rest of the higher ups were always looking for an excuse to execute him (the opportunity presented itself in the form of Xia).
Psychology/Character: Arane, although appearing like a sociopath, in reality is a very insecure individual deep within his ‘empty’ soul. He enjoys the sight of blood because it is a common proof of life and its fragility. He is incredulous when his own blood is drawn (and to some extent enjoys it) as it reminds him that he is a living and breathing being (albeit immortal). His mind is naturally chaotic since he is a being of Chaos and therefore it is only natural that he is in many ways ‘insane’.
Having no one to depend on or form ‘attachments’ with (unlike Terra Stelio with Risenden), Tela Serus had a very lonely ‘childhood’ (or whatever the equivalent is for Lizards and Phoenixes). The only reason he knew of loneliness is because he always compared himself to Terra Stelio and saw himself as a failure. Eventually, he resorted to teasing/torture (depending on the severity of ‘teasing’) as a way to gain attention; the same goes for causing mischief.
Developed a trickster personality after becoming the second Guardian and being manipulated by humans for their own gain. Eventually came to hate humanity and wished for nothing more than its destruction, thus him joining the human Order who wished to destroy the (Chaos) universe.
Relationship with Xia: First noticed because of the strange appearance (blue hair and mismatching eyes). First became actually interested once he found out that she was on the Glenton case. Subconscious prodding from the Godmother made him go to the extremes of teasing Xia. Her reactions however captured his interest so he carried on to do so by his own will.
Liking to be in control of the game, he sees Xia initially as one of his many pawns. Pawns however can become queen once reaching the end of the game. Being the game master, however, Xia instead is promoted to rook (credit for original chess reference: Pearson brat), necessary and most precious but sacrificed when desperate times hit. Attachment being the strongest emotion of Phoenixes and Lizards, however, Arane was unable to carry on living without Xia. He counted on the Godmother’s eventual calming down and mercy to give Arane and Xia a second chance in their next life.
