In the spring of 2018 three of the band members together with three guest performers presented in front of public the drama called Rock Theater 'Asparuh - the Battle of Ongal' written by Simeon Hristov. In this project the same performers play the theatrical roles, sing the songs and play the instruments. The text was based on the very new researches about the Bulgarian medieval history, religion, state organisation and relations with the Eastern Roman Empire. Later in the same year the band recorded their new songs with the singer Simeon Angelov who performs the role of Asparuh in the aforementioned rock theater and who is deputy director of a school in Sofia as well as a singer in an orthodox church choir. The new songs together with two of the already recorded songs - 'The laws of Krum', and 'The city of Asen' become part of the album "The great rulers" which is dedicated entirely to the Bulgarian medieval rulers (Tervel, Omurtag, Simeon, Samuil, Kaloyan, etc.)
