Wardruna is a Norwegian musical project founded by Einar Selvik in 2003. The project's music is often classified as Nordic folk or dark ambient, drawing heavily from Norse mythology and ancient Norse cultural and spiritual traditions.

Einar Selvik, along with other musicians, creates music that is deeply rooted in historical and cultural authenticity. They use a variety of traditional instruments and techniques, including runes, ancient Nordic instruments like the tagelharpa and goat horn, as well as ambient sounds from nature.

Wardruna gained significant attention for their contributions to the soundtrack of the popular television series "Vikings," which brought their music to a wider audience. Their albums, including "Runaljod – gap var Ginnunga" (2009), "Runaljod – Yggdrasil" (2013), and "Runaljod – Ragnarok" (2016), have received critical acclaim for their evocative and atmospheric compositions.

Wardruna's music is known for its immersive and spiritual qualities, often transporting listeners to ancient landscapes and invoking the mysteries of Norse mythology. They continue to tour internationally and are highly respected within the neofolk and Nordic music communities
