— Sierra Mikain
Sierra Mikain is the original bearer of the Moon Rune, discovering it in the year -375. The rune was so powerful that Sierra was able to create an entire coven of lesser vampires using the rune. Sierra and her followers lived in happiness in Blue Moon Village, until about 400 years ago when a young member named Neclord stole the rune and ran away. With the rune gone, the blood lust of the vampires was now out of control, driving many to prey on humans for sustenance.
Sierra pursued Neclord, along with other vampires that preyed on humans. Prior to arriving in Tinto Principality, while journeying to the City-State of Jowston, she had met with Nash Latkje and together the two defeated Rein Penenberg, a former lover who had turned to feasting on humans.
Later during the Dunan Unification War, when Neclord attacked Tinto Principality, Sierra joined forces with the New State Army to defeat him. Sierra was able to sense the Moon Rune's location and was able to reclaim it from Neclord at Tinto.
Afterwards, Sierra remained with the New State Army. Following the war, she decided to remain with humans, feeling no hurry to return to Blue Moon Village.
