Baek Ryun

Backryun is the Ruler of the Seventy-Seventh Floor and a good friend of Urek Mazino. He helped with the formation of Walhaiksong. He is one of the Walhaiksong's leaders and most gifted Wave Controller in the Tower's history.

Background
Backryun was born in the middle region as an orphan and roamed without a residential card. Eventually he went into a forest to avoid contact with others. Becoming one with the forest, he lived there for a long time, naturally learning to control Shinsoo (which implies he controlled Shinsoo without a contract). Later, Headon, interested in Backryun's abilities, picked him to become a Regular. As a Regular, he quickly became a Ranker, but then returned to the forest without any activity. After returning to the forest, he spent a long time gardening the forest. His forest, which was like a living animal, is said to emit a mysterious atmosphere.

Urek Mazino, who at the time was climbing the tower, heard of Backryun's forest. He visited Backryun, and they eventually became best friends. Backryun was especially interested in the world outside the Tower that Urek often spoke of. Hearing Urek's stories, Backryun dreamed of living in the world outside of the tower. After Urek Mazino left to climb the tower again, Backryun's ambition continued to grow. He then later confessed his passion to leave the Tower to Urek Mazino who returned as a Ranker. Urek, delighted by his confession, asked Backryun to leave with him. However, Backryun declines the offer, saying that he cannot leave the forest which was like his own life. It is told that Urek Mazino, pounding his chest, then said this.

"Then I will give this forest a pair of wings." "I will make it so that these trees can follow you everywhere."

Backryun thought Urek was just rambling because Urek was drunk; however, Urek was serious. He absorbed everything in the forest as he shouted like a thunder, Eventually, the enormous forest shrunk to a size of a fist.

Urek then gave the compressed forest with wings in a box to Backryun. Backryun was very surprised and grateful; however, there was a problem. The compressed forest was too heavy for Backryun to carry, so Backryun gave the box back to Urek. This winged box became Urek and Backryun's symbol of friendship. Later, the forest was moved to 77th Floor, Rankers who heard of Backryun and Urek gathered to the forest, eventually forming 'Walhaiksong' with Backryun as its leader.

Appearance
Backryun's real appearance is controversial. He normally appears to be an ordinary boy, but he sometimes appears as a tall young man. Some say that they have seen him in a form tall enough to touch the ceilings of the Tower.

Abilities
Backryun is a High-Ranker who is praised for his influence over his battle abilities, and it cannot be said that his battle power is lacking. Though Backryun is a Wave Controller who controls the battle and supports team members over attacking others directly, his hand-to-hand combat ability is said to be impressive. However, since he only fought a limited number of battles with High-Rankers, his combat abilities may need to be verified.
