“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.

Profile[edit | edit source]

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.

In Fire Emblem Heroes, there are two variations of Sieglinde, each serving as the unique weapon of a different variation of Eirika. The original Sieglinde is the basic Eirika's primary weapon; granting the girl Hone Attack 2 as an in-built weapon effect, letting Eirika buff her adjacent allies at the start of the turn for +3 attack. After the weapon is refined, this is improved to grant +4 attack, equal to Hone Attack 3. On top of this, if Sieglinde is refined for additional effect rather than stats, it gives Eirika an in-combat boost to all of her stats equal to the highest visible stat boost per stat on any ally within two spaces. Each stat checks independently.

The Storm Sieglinde functions as the unique weapon of Eirika (Graceful Resolve), the Legendary Banner-exclusive Eirika. This variant of her sword boosts her attack by a flat +3, while it enhances her defensive capabilities in combat as long as her foe has more allies within two spaces than she does. These boosts include a boost of +3 for both her defense and resistance and negating her opponent's special charge from each of her attacks.

Etymology[edit | edit source]

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").
