The Earth Sword (大地の剣 Daichi no ken) is a magical Sword that hails from the Jugdral Series of the Fire Emblem Series. Bequeathed upon Lachesis as a parting gift from Eldigan and inherited by her daughter, Nanna, this sword possesses the unique ability of allowing its wielder to drain the HP of a selected enemy unit in order to restore his/her own. The sword is specifically bound to Nanna in Thracia 776, a distinct projection of its role as a treasured keepsake, by which she preserves the memory of her departed mother.
The Runesword induces an effect that is similar to the Earth Sword, and may thus be perceived to be its modern incarnation. They both also share their animation with Nosferatu as well.
