After Aquila was replaced by Vulpus, the band released it's first official demo in the beginning of 2009. In the year 2010 the band entered Sounds Great Promotion studio, recording the first 4 tracks that will end on the Ars Sathanae debut album. Iubaris played many live shows across all Poland, and participated in different independent metal festivals. They performed with bands like Christ Agony, Furia, Fulcrum, Unborn Suffer and Pleroms Gate. In February 2012 Erthun decides to leave the band for personal reasons, and is replaced by Mjolnir.
