Doomsword's lyrics are concerned with epic themes such as ancient and medieval history, fantasy literature, and European mythology.
The original members of the band, Deathmaster and Guardian Angel, were already working together on an ancient music project called 1014AD with strong medieval influences, and after a short hiatus they re-arranged the 1014AD material into proper heavy metal songs, and released them as a demo called "Sacred Metal" the same year.
In 2002 DoomSword broke their live "silence" by playing a gig with Manilla Road in Porto D'Ascoli, Italy, and subsequently taking part to important underground metal festivals such as the Keep It True, Bang Your Head, Up The Hammers, Headbangers Open Air etc.
As mentioned on their official site, DoomSword adopted pseudonyms in 1997 to reinforce their bond with their main influence, US metal band Warlord.
The pseudonyms Deathmaster and Guardian Angel are taken from names carved on headstones in the cover painting of Warlord's "Deliver Us" EP.
