Morgana Lefay (known as Damage from 1986 until 1989) is a power/thrash metal band from Bollnäs in Sweden. It is named after Morgan Le Fay of the Arthurian cycle. They independently released their first album, Symphony of the Damned, in 1990. The success of Damned allowed the band to tour and eventually landed them with Black Mark records. In May 2006, drummer Robin Engström left the band because of 'personal differences'. Later that month, Pelle Åkerlind became the new permanent drummer. In late August 2006 the band went into Studio Soundcreation to record a new album (titled Aberrations of the Mind), it was released on March 19, 2007. It was the first album with Åkerlind on drums.

Morgan le Fay , alternatively known as Morgan le Faye, Morgen, Morgaine, Morgain, Morgana, Morganna, Morgant, Morgane, Morgne, Morge, Morgue, and other names, is a powerful enchantress in the Arthurian legend. Early works featuring Morgan do not elaborate her character beyond her role as a fay or sorceress. She became both more prominent and morally ambivalent in later texts, in particular in cyclical prose works such as the Lancelot-Grail and the Post-Vulgate Cycle, in which she turns into a dangerous arch-enemy of King Arthur and an antagonist of some tales.
