The Beo Sword (ベオの剣 Beo no ken) is a special Sword that is unique to Fire Emblem: Thracia 776. This sword can only be used by Delmud and Felgus, both of whom are hinted to be the offspring of the philandering Beowolf, postulating them as half-siblings. When equipped, it grants the Wrath and Ambush skills to its wielder.
|Effect(s)||Bestows the Ambush and Wrath skills upon its wielder, as long as it is equipped.|
* - Usable by Delmud and Felgus only.
The "Beo" portion of the sword's name could possibly be derived from Beowolf's name, further hinted at by his alleged children, Delmud and Felgus, being able to wield it. An alternate translation of the name could be "Beo's Sword", further implying, at the least, that is was owned by someone with the name or a name similar to "Beo".
Alternatively, the name of the sword could take its origins from the Irish verb "beo", that which directly translates to "live".
