Biate Ellon

Biate Ellon was the first human to make a contract with a spirit king. She was known as the "Queen of Water."

Background
After forming a contract with with spirit king, Ellaim, she became one of the strongest humans. Thus, she was repeatedly pestered by Reid Flamdor who wished to defeat her and officially gain the title of the strongest human. However, she turned him down as her nature was calm and gentle and she didn't like conflict.

Around 50 years ago, however, he appeared at Maiel mountain range in the southern region of Rinse Kingdom after finding out that her dwelling place was inside Maiel mountain. He requested for a duel but she simply served him some tea and declined indirectly. In the end, he attacked her and forced her to battle him. The two fought for four days and four nights inside her dwelling place. Reid Flamdor believed that he was the strongest among humans. However, during the fight, he was never able to overwhelm her even once. In the end, he, who became blind due to his competitiveness, used lethal secret art. At that moment, the duel that was looking for who was superior ended up being a life and death one.

In the end, both gained nothing but injuries and realized that they wouldn't survive due to their severe wounds. Biate Ellon summoned the water spirit king Ellaim who her to Poskein Lake where she wished to take her last breath. Despite Reid Flamdor's reckless act that cost her her life, she forgave him.

Previous Timeline
Since Viscount Potter's soldiers were unable to obtain Reid Flamdor's diary which recorded the fact that Biate Ellon's dwelling was right behind the cave, no one entered her dwelling and Biate Ellon name never came up in the world again.

Current Timeline
Roan managed to obtain the complete technique and also the Reid's Art of Fighting technique. In addition, after reading Reid Flamdor's diary, he realized that Biate Ellon’s dwelling was most likely right behind the cave and managed to enter it due to unconsciously absorbing Ellaim's Tears. There, he learnt that Biate Ellon’s remains were in Poskein Lake and planned to visit it in the future. Due to being stuck in the cave, he decided to begin his mana training for 20 days until Viscount Potter's soldiers left Maiel mountain.

Due to him absorbing Ellaim's Tears, he was saved by Ellaim, who following Biate Ellon's final wish agreed to save the future owner of her Tears once. When he was rampaging around after having lost his mind at the death of Rose Troop, she appeared and quelled the chaotic Flamdor Mana Technique. She left the remaining essence of water around his mana hole so that it may quell the Flamdor Mana Technique in case it ran haywire in the future. Due to this, the Flamdor Mana Technique's chaotic nature was greatly subdued and Roan's mana became much more stable at the cost of becoming slightly slower.

While fighting a Sethus at Poskein Lake, Roan was sneak attacked by it and fell in the water. Just when he was losing hope due to his empty mana hole and the monsters surrounding him, a blessing in disguise took place. Due to Roan's mana hole being empty, the water essence that Ellaim had sealed outside his mana hole to quell his mana in case Flamdor Mana Technique ran wild again was absorbed by Roan and it reacted to Biate's hidden piece that was deep within Poskein Lake. Thanks to this, Kinis grew multiple times and became much stronger than before. Roan also became able to use the water mana with the use of Tale Mana Technique that Brian Miles had recently created.

Eventually Roan realized that the trick to use his water mana was to empty out his fire mana. This led to him becoming much more powerful as his mana reserve grew immensely and he became able to use techniques wither higher mana requirements more freely.
