In December 2016, Italian dark ambient musician Maurizio Landini self released the ep Ancestry under his moniker Onasander. The compositions on the original ep was inspired by the military history of the Roman Empire. The battle of Milvian Bridge for example which manifested Constantine as the sole rule of the Roman Empire. 

Four artists were asked by Onasander to give their interpretations on his compositions. 
Ajna, Hilyard, Klangbunn and Xerxes The Dark answered the call.
