Scardust began, under the name “Somnia”, in 2013 as a duo project, when the musicians Orr Didi and Noa Gruman wrote a rock opera called Gates of Dawn. The opera was arranged for a full symphony orchestra, choir, and metal ensemble. A demo was fully recorded at a home studio quality, but due to technical reasons was not yet recorded professionally and officially released. The single from the opera, Betrayal, can be found at the Somnia's channel on YouTube.

With the addition of drummer Yoav Weinberg and bassist Yanai Avnet, Orr and Noa decided to put Gates of Dawn on the music that would become their EP "Shadow", with the further additions of guitarist Yadin Moyal and keyboardist Lior Goldberg.

With the release of this EP, the band learned that someone else had the trademark for the name “Somnia”, and so they became - as they are currently known Scardust.
