Major Spoilers Ahead

Solar Note: At the moment, all of the following images I found online. All credit goes to their artists. Hope to commission artwork for the Pillars in the future.

Rat Pillar(s):

Ratmir Hoshizora- Younger brother of Reginald. As a kid he used to rid on top of his head. Like Daisaru, he was sealed up by the ancient Xianese people of Xeleria. Unlike him, he's yet to be found. No one knows where his resting place is. His sword is known as 'The Blade of Ruin'.

His special ability as the rat pillar is the same as his niece.

Rocio Karashi Kuroriku of Sun- Second daughter and third child of Reginald. Can use fire. Since her older brother is a traitor and her older sister is mentally unstable, she's the one slated to inherit Abyssia upon the passing of the Four Rulers and the slumbering or death of Reginald. She's a priestess of Ein, the primordial God of Darkness. It appears that she's the reincarnation of a princess of Xian.

Her special ability is the absolute invisibility. No one can detect her nor her energy. Lasts a short time.

Ox Pillar:

Reginald Hoshizora of Kuroriku- Leader of the Pillars and Chosen of Darkness. He's one of the four remaining Ancient Pillars, the founders of this order of knights of Abyssia. His twin brother was the Chosen of Light. His fate is to serve and awaken Ein. As the leader of the Pillars, he gave each one one of the gifts/special abilities. At the moment, the majority are his children. Six being from his first wife, Tulia Kuroriku, the two from his second/current wife, Aster.

His special Ability is necromancy though he theoretically can use all of the others' special skills if the abilities are returned to him or the others perish.

Tiger Pillar(s):

Maison Hoshizora- The oldest of Reginald's children with Aster. Like his sister, he's from another time, except he decided to remain in the time he'd traveled to. He has two children. Reginald is considering having him hand over his position to Serrano like how his sister gave hers to Calamity.

As a Hoshi he can bend space-time. He has the special ability of 'Construct' meaning he can create anything he desires as long as he can imagine it with immense detail. 

Rabbit Pillars:

Kaguya Hoshizora- A mysterious girl who is said to come from another time. She's the daughter of Reginald and Aster. She was named after Kuroriku's capital city.

Her special abilities include; creating a tower with special qualities; awakening the hidden potential in a person; and being able to manipulate memories. She gave Conrad the former two.

'Calamity' a.k.a. Conrad Nightshade Kuroriku- Kaguya gave her spot to Calamity after she returned to her original time. He is Serrano's late brother, brought back to life by Reginald. 

Kaguya gave him two of the Rabbit Pillar's three treasures, those being the ability to awaken hidden potential and the ability to create a tower with special properties. Whether he even knows how to use them is unknown.

Dragon Pillar(s):

Margaret Nathair of Zettai- Dragon Pillar. She and her brother are part demon. Has the highest natural defense out of all the Pillars. She's the grandmother of Shin'en, Maki, Kei, and Koukyuu.

Her late brother, Orochi, was one of the founders of her husband's clan, having given his power to the eighth branch. Reginald is considering to replace her with his grandson, Tetsuya.

Special ability is increasing one's natural defenses by three times their normal threshold.

Snake Pillar:

Collin Nathair- The youngest of the four Ancient Pillars. The younger brother of Margaret and Orochi. Unlike his siblings, he's rather gentle-mannered. Every one-thousand years or so, he reverts back into a child. Due to this cycle, his power isn't waning, unlike his fellow Ancient Pillars. This is a natural ability.

His special ability is turning people into stone by touching them or with his eyes.

Horse Pillar(s):

Jun Hao Situ- Ancient Horse Pillar. He went into slumber several years ago. He passed on his title to his daughter before he did. He was a loving husband and father. One can say that he spoiled his daughter. When transforming, he tended to do so halfway, causing him to have the appearance of a centaur.

His special ability is unknown.

Daiyu Vega Zhima Situ Ikeda of Kuroriku- She replaced her father as the horse pillar following his slumber. She carries herself in a noble manner. She's the only Abyssian-Zionian hybrid among the pillars who isn't Reginald's child. She's the mother of Roa and wife of Skah, the Rooster Pillar. Her special ability is unknown.

Monkey Pillar:

Daisaru a.k.a. Sun Wukong- The legendary Monkey King. He has a lot of natural abilities, including immense physical strength, that he doesn't see the need to even use his special ability. Grew up in a forest in Xian.

Special ability is to remove all senses from a person. The longer it lasts, the more the psyche of his opponents becomes strain. Most can't handle even a few seconds of it.

Sheep Pillar(s):

Woolsey a.k.a. Wulfsige Thyme Kuroriku- Rocio's youngest full-blooded brother. He's also her favorite. Despite being the sheep pillar, he has a wolf motif. He enjoys facing off against strong opponents.

Special Power: Dominion over dreams.

Rooster Pillar(s):

Skah Altair Oregano Kuroriku- 

Previous winner of Spirit Duels and the current Rooster Pillar. The younger brother of Takeshi, Selena, and Rocio. Older brother of Woolsey, Plum, Maison, and Kaguya. He is warm and kind. His hobbies are playing card games, dancing, and playing instruments, all of which he is very talented in. He usually tends not to fight but he is very nimble. When truly angered, one must be cautious. He has an array of natural skills, many of which involve fire.

His 'true form' resembles the 'August Rooster' aka the Fenghuang.

His special ability allows him to hurt others with his voice but it'll also affect him.

Dog Pillar(s):

Selena Jasmine Kuroriku- Mother of Serrano. Despite not actively helping Abyssia, she still retains the position of Dog Pillar. Once a cheerful person, she's now a shadow of her former self.

Her special ability is unknown.

Pig Pillar(s):

Plum Kuroriku- The latest Pig Pillar. The last child Reginald had with Tulia. She was born on the day of her mother's death. Despite this tragic event, she's a cheerful young girl with a child-like glee and personality. She likes Collin. Controls Water.

Special Ability: Can peer into one's deepest desires and creates highly realistic illusions of them.

Cat Pillar:

Kuroshi a.k.a. Takeshi Lavender Kuroriku- Father of Tetsuya and the last Pillar of Destruction. He's the oldest of Reginald's 8 children. He betrayed his father and the others by crafting the weapons of the Five Knights of Prophecy and plotting against them. He was once one of the Seven Hills, owning Serrano's Aventine. His 'true form' resembles a cross between a black house cat and a jaguar.

He claims his special ability is energy absorption.
