The band was formed in 2002 by drummer Frank Andiver (Labyrinth, Wonderland, Shadows of Steel) and guitarist Emi Manuguerra (Angel Grace), who sum up Sigma singer Val Shieldon, Seven Gates Keyboards player Fabrizio Marnik and Shining Fury’s bass Alessandro Cola.
The influence of prog/power metal is clear right from the first compositions that portrayed the first full length DEEP INSIDE (King/Scarlet Records), licensed in 2005 and claimed as one of the 2005 most interesting metal works.
The band stopped for a while, due to the split of Emi Manuguerra, Fabrizio Marnik and Val Shieldon, longing for other projects. Frank Andiver and Alessandro Cola called then guitarist Tommy Pellegrini coming from Shining Fury, to start working on the following of Deep Inside; the band is completed by guitarist Vic Mazzoni (Projecto, Wonderland) and singer Wild Steel (Shadows of Steel) for the recording sessions, but the premature, unexpected passing of guitar player Vic, leave the band in an apathic and frustrated mood that last until 2017, when Oracle Sun gathered up their broken bones and found in Alessio Pascucci (keys) and Giacomo Paradiso (guitar) a new lifeblood to continue and finish what was started.
Songs have been recorded and rearranged again.
