The Empire Strikes Back Monthly 149: Death Masque is one of first stories to take place after Star Wars Episode V: The Empire Strikes Back.
Death Masque was one of the few original stories published in the UK series. Unlike the other original stories, it was not reprinted in the Classic Star Wars: Devilworlds series. For over 30 years, it and the 1988 Ewoks Annual were among the only licensed Star Wars stories in any medium to never be officially released in the United States. It was finally collected in Omnibus: Wild Space Volume 1 in 2013.
