Ash is an adopted daughter of Vanir, a top-rank mage known for her ability to manipulate time as well as the last descendant of the ancient lineage of time manipulators and clairvoyants, The Arcanias. She serves as the seer of Urth Village. About six years ago, Ash was found unconscious and severely wounded by Orpheus, Vanir's familiar on Lacus Fleur a place that is located on the outskirts of the village, where mysteriously huge flowers grow on lake waters. She was then brought in a nearby abandoned old church where Vanir and Orpheus live. When she finally gained her consciousness, she found herself in a very unfamiliar place, and staring at her are two unfamiliar faces, much more was then she realized
she has no memories at all. Everything was later explained by Vanir. Since then,she started a new life with Vanir and Orpheus. Vanir gave her the name Ash, as to compliment her hair.
As a child, Ash never had any friends since Vanir prohibits her from roaming around the village. So Ash spends her time reading wizardry books, where little by little, she learned sealing magic. Oftentimes she also plays by herself on Lacus Fleur somewhat hoping to remember her past. Till she accidentally met a boy named Kuean who's wandering around the area. The two later became friends and often secretly meets at Lacus Fleur. Once, Kuean told Ash about a certain myth. According to the myth, angels that inhabit on land were thrown out of the heavens because they had angered the gods. It is also said that fallen angels will cause misfortunes to people around them. That myth made Ash realize that Vanir, from the beginning has been trying to protect her, for once the village people knew about her existence, they'll certainly resent her.
Few years passed and Vanir's body started deteriorating which caused lots of people to worry and visit her place. Eventually, Ash was discovered. The people then assumed that she's the reason for why Vanir, though at a considerably young age, is nearly dying. Although Vanir tried to defend Ash, they never listened and soon they plotted to kill Ash. Knowing what was going to happen, Vanir used the remaining strength left in her weak body and left Urth together with Ash and Orpheus. However, Vanir's life won't last any longer so she made a decision and broke the greatest taboo among the Arcanias, she passed on her bloodline to Ash, sealing it on her left eye. Ash having no clue what Vanir was doing, had felt a striking pain through her brain and began seeing fast-appearing visions of her past, that make no sense at all. Among those visions, was a hazy figure of a black-winged boy bidding her "good night" that appears to have been important to her. Ash has then returned to her senses and noticed that Vanir's tatoo had vanished. Having to witness Vanir slowly dying was really painful for her and started to believe the myth even so, Vanir told her not blame herself, for Arcanias, unknown to most people, are fated to live short lives. Vanir entrusted Ash to Orpheus then wishes them to live in peace and before she took her last breath, she revealed Ash' real name. Seira El Claustrum. Though Ash was shaken after hearing it, she was more overwhelmed with feelings of sorrow and grief
After mourning for Vanir's death, the two set out on a journey, in search for the boy she saw on her forgotten past who might lead to her real identity
