Legacy of the Dark Lands is the eleventh studio album by the German power metal band Blind Guardian, released on 8 November 2019 through Nuclear Blast.

It marks a departure from all previous works, as the only instruments performed are those of the Prague Philharmonic Orchestra, with singer Hansi Kürsch being the only member of the band to perform on the album; due to this, the album is credited to the "Blind Guardian Twilight Orchestra" instead of Blind Guardian.

A project worked on by Kürsch and André Olbrich since 1996, it is a concept album set in the 17th century during the Thirty Years' War, and based on the character of Solomon Kane created by Robert E. Howard in 1928; in Legacy of the Dark Lands, Kane's daughter, Aenlin, is looking for her father's legacy in the Habsburg Empire.

"[2] Olbrich stated: "When I got stuck during writing a Blind Guardian record, I would simply work on the orchestra project, and it cleared my mind fairly quickly.

The two are hired by the Danish West India Company, and their group, led by a man named Nicolas, must face demons trying to use the conflict for their advantage.
