Omega was formed in 2012 by some members of already active bands (Hanging Garden, Nostalgie, Deadly Carnage, Ashes of Chaos). During the first four years of activity, the band decided to work on their music without any presence on the web and without exposing them to the public. In 2017 they released their first album "Eve", a concept based on the Voynich Manuscript.
In 2021 the band back with a new concept album with the hermetic title "Nebra".
