“The Sacred Twin storm blade. Str +5.”
—In-game description

Sieglinde (ジークリンデ Jīkurinde) is a sacred Sword that hails from Fire Emblem: The Sacred Stones and Fire Emblem Heroes. Also called the Thunder Sword (雷剣, Raiken), Sieglinde, alongside the Flame Lance Siegmund, is one of the Sacred Twins of Renais, and is solely usable by Eirika. Like most of its counterparts, Sieglinde has the ability to inflict effective damage against monsters.


This sword is, alongside its sister weapon, introduced after the battle against Orson in Chapter 16. After taking the Sacred Stone of Renais and allowing their braces to resonate with it, Eirika and Ephraim are guided to two Chests that are located nearby. Seth then unlocks both chests, takes both Sieglinde and Siegmund from them, and gives the former to Eirika. In response to being given the blade, Eirika resolves to use the terrible power that is contained within the blade in order to restore peace to the world.

Sieglinde is the long-lost twin sister of Siegmund in Richard Wagner's opera The Ring of the Nibelung. When the twins reunite in adulthood, they fall in love and commit a taboo by bearing a child together. She is an amalgam of the characters Signý and Hjördís from the epic Völsunga Saga and Sieglind from the equivalent German epic Nibelungenlied.

The name Sieglinde is a Germanic name comprised of the roots sigu ("victory") and linde ("gentle").
