Amberian Dawn于2006年成立于芬兰，所有团员都有过组团经验，主音吉他及键盘手Tuomas和贝司手Tommi都是前新古典Project"Virtuocity"的成员。2006年曾发行过一张小样，《River Of Tuoni》这张专集是乐团的首张正式专辑。乐团风格立足于旋律金属，新古典及能量金属。
Several of the members that would later form Amberian Dawn previously played in the group Virtuocity, and after Virtuocity's breakup they formed a new band, based on keyboardist and guitarist Tuomas Seppala's songwriting. The band was named Atheme One and had Peter James Goodman as their lead singer and lyricist. The band released a demo in 2006 featuring four songs, "Dreamchaser", "Velvet Roses", "Burning Touch" and "World of Insanity", three of which would later be remade into Amberian Dawn songs: an instrumental version of "Dreamchaser" appears as a bonus track on River of Tuoni, "Velvet Roses" appears with lyrics by Heidi Parviainen as "Sons of Seven Stars" on The Clouds of Northland Thunder and "World of Insanity" appears with new lyrics as "Ghostly Echoes" on End of Eden.
