The Falchion (ファルシオン Farushion) is a divine Sword that appears in the Akaneia Series and Fire Emblem: Awakening. Forged from a fang of Naga upon her departure from the realm of the living, this weapon is imbued with the power to slay dragons, and has, throughout its various incarnations, proven pivotal in vanquishing end-game antagonists, including the likes of Medeus, Duma and Grima. The sword is solely bound to Marth, Alm, Chrom and Lucina, and confers upon them the ability to recover their HP when it is used as a normal item.
In Awakening, the blade has several incarnations, each one named differently: in its sealed form, it is known as the Sealed Sword Falchion (封剣ファルシオン Fūken farushion) in the Japanese version of the game and simply called Falchion in the English release; once awakened by Naga, it is referred to as the Exalted Falchion (神剣ファルシオン Shinken farushion, lit. Divine Sword Falchion); and the version used by Lucina is called the Parallel Falchion (裏剣ファルシオン Uraken farushion, lit. Hidden Sword Falchion, or more loosely "sword from the other side"), referring to the fact that it is similar to Chrom's and from another timeline, although it is different statistically, being superior to Chrom's sealed version and inferior to the Exalted Falchion.
The Falchion blade was once wielded by the hero Anri to defeat the dark dragon Medeus and halt his reign of tyranny. Later, in the events of Fire Emblem: Ankoku Ryū to Hikari no Tsurugi (and all subsequent remakes and sequels), Marth, the descendant of Anri, removes it from its resting place upon defeating Gharnef, and, in the footsteps of his predecessor, employs it to defeat Medeus and end his quest to bring the world to destitution.
In Fire Emblem: Shadow Dragon, it is possible for Marth to procure a weaker version of the Falchion from Nagi. While the origins of this version are unknown, it is probable that it was forged from one of Nagi's, a lesser divine dragon, own fangs. In addition to being weaker than the original, this version of Falchion is also significantly heavier and more cumbersome to wield.
Yet another duplicate of the Falchion blade also exists within the same realm, as can be gleaned from Fire Emblem Gaiden, where it is wielded by Alm, who employs it to defeat Duma. In this case, the sword is not contrived from the fang of a dragon, but instead forged with the conventional base material of metal. It is then imbued with special incantations in order to imprison the goddess Mila. While her soul is successfully sealed within the sword's core, the same cannot be said about the power that she once wielded, which gives the sword its potency.
The Falchion reappears in Awakening, where it is, alongside the Fire Emblem, one of the royal treasures of Ylisse, and is the personal weapon of Chrom. In the later parts of the game, the seal suppressing the powers contained within Chrom's Falchion is released by Naga, transforming it into the Exalted Falchion. This game's version of the blade resembles the one originally wielded by Marth, with the exception of its hilt: the original hilt comprises a guard embossed with a curved, wing-like finish, a ruby in the middle, and an emerald studded into the pommel, while in Awakening the guard is ridged and surrounds a teardrop-shaped hole, the grip is reddish-brown, the pommel is crown-like and has no gem, and a strip of gold runs down the blade, filling in the fuller. The discrepancy in its appearance across time is explained by Lucina in her supports with Owain: the hilt (along with the entirety of the Shield of Seals) has gone through repeated breakages and re-forgings over the centuries. The blade itself is immune to the ravages of time and will never rust or dull, hence its pristine appearance.
An alternate version of the Falchion is brought into Chrom's timeline by Lucina, where it is referred to as the Parallel Falchion. According to Lucina's supports with her sibling, only those descending from Ylissean royalty possess the potential to wield the Falchion, and on top of that, the spirits inhabiting the blade are selective about whom they deem worthy. Those not deemed worthy will, according to Lucina, find that it is dull in their hands, so much so that they are incapable of performing menial tasks like chopping wood with it. In the final support conversation Lucina shares with her sibling, her sibling is revealed to have, albeit unwittingly, been accepted by the blade. However, no form of the Falchion in the game can be used by anyone other than Marth, Chrom, and Lucina.
The Falchion appears as a piece of treasure in the Great Cave Offensive, where it is worth 375,000 G. It is correctly named in the Japanese version, but the English localization did not pick up on the reference and renamed it to "Sword."
In the Super Smash Bros. series, the Falchion is the insignia representing all characters hailing from the Fire Emblem series.
The Falchion is the main weapon of Marth in allthree of his appearances in the series. Its design is similar to the Falchion's first design from Fire Emblem: Ankoku Ryū to Hikari no Tsurugi, though with some minor redesigns in each game. Marth's Falchion deals more damage if the opponent is struck by the tip of the sword.
The Falchion, in its Fire Emblem: Awakening form, is Lucina's main weapon in Super Smash Bros. for Nintendo 3DS and Wii U. Unlike Marth's Falchion, Lucina's deals equal damage no matter what part of the sword hits the opponent. Chrom also wields his Falchion during Robin'sFinal Smash.
The Awakening version of the Falchion makes a cameo appearance as a part of the Fire Emblem crossover for Monster Hunter Frontier G. Chrom's regular Falchion and Lucina's Parallel Falchion are the base versions of their weapon set. If forged and upgraded, Chrom's Falchion will turn into the Exalted Falchion, complete with the same golden glow on the blade while Lucina's will upgrade to an improved Parallel Falchion with a silver glow.
Despite its name, the Falchion is not actually a falchion, but a two-handed medieval longsword. A real falchion is curved and single-edged, more akin to a scimitar or a machete.
To commemorate the launching of Shadow Dragon, Nintendo had an actual sword forged in the likeness of the Falchion.
During Cornelius's fight with Gharnef in the Fire Emblem OVA, the Falchion is depicted as twice its original size, in stark contrast with the OVA's VHS cover and its appearance in the games themselves.
In both Shadow Dragon and Shin Monshō no Nazo, Marth displays no unique animations while wielding the Falchion.
In its Awakening manifestation, the markings on the Falchion read "Sniamer llits erutuf eht tsol si esle lla nehw", which, when reversed, is "When all else is lost the future still remains".
In Awakening, a blue glow fills up the teardrop-shaped hole in the sword during certain points in the story, although the reason for this is not revealed. It has been theorised that this phenomenon occurs each time history is rewritten.
In Awakening, despite the Parallel version being the same one as Chrom's (as Lucina inherited it upon his death in the future), he cannot wield it.
