Onoskelis Long Sleeve Shirt

A long sleeve inspired by the atmosphere of dungeon synth and raw black metal recordings, referencing Onoskelis and The Hecate Prophecies in your Cold Throne.

The artwork follows the aesthetics of underground tape culture — lo-fi imagery, mythological themes, and medieval darkness shaped by early black metal while drifting into the colder, more isolated world of dungeon synth. Atmospheric rather than aggressive.

A piece that feels closer to an obscure cassette release or xeroxed zine than standard merch.
