This is what we found on Wikipedia regarding the The Imperial:

Imperial Age is a Russian symphonic metal / power metal band, currently based in Northampton, England. The band was originally founded in 2012 in Moscow, Russia by singers/composers Alexander "Aor" Osipov and Jane "Corn" Odintsova, who relocated to Turkey, and later the United Kingdom, following the Russian invasion of Ukraine. Today the group has musicians from Russia, the United Kingdom, Italy, the Netherlands and the United States, and their music is primarily in English.

In January 2023 Jane and Alexander were endorsed by Arts Council England as Exceptional Talents and applied for UK residency while living in Turkey, where they moved to as soon as the war began. A crowdfunding campaign set up to aid their relocation has gathered £21,419 in pledges from fans. Their residency was granted by the Home Office and they moved to London on 17 April 2023.

Imperial Age has collaborated on multiple occasions with musicians from Therion and Arkona who are featured on all Imperial Age albums. The band was brought to international attention by symphonic metal pioneer Christofer Johnsson, who, after being impressed with their live performance and their cover of Therion's song To Mega Therion in 2014, offered to distribute their music through his label Adulruna Records.

The name of the band has nothing to do with modern states and refers to Atlantis and Hyperborea, from which the musicians derive their inspiration. The lyrics deal with magic and the occult, mainly Hermeticism, Hermetic Qabalah, Runic magic, paganism, bon and the legacy of Ancient civilisations such as Ancient Egypt, Sumer and Mesoamerican civilisations.
