“The Sacred Twin storm blade. Str +5.”
Sieglinde (ジークリンデ Jīkurinde) is a sacred Sword that hails from Fire Emblem: The Sacred Stones. Also called the Thunder Sword (雷剣, Raiken lit. Thunder Sword), 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 and Siegmund are the only Sacred Twins that possess similar names, with the only difference setting the two apart lying in last 4-5 letters making up their names.
The Sieglinde blade most likely derives its name from the woman of the same appellation in Norse Mythology. Sieglinde is said to have engaged in an incestuous relationship with Siegmund, a relationship that saw the conceiving of a son, Siegfried.
