Star Dragon Sword

The Star Dragon Sword is a weapon and physical incarnation of the Night Rune appearing in Suikoden I, Suikoden II and Suikoden III. A cocky being who transformed into a sword following severing its bonds with the Sun Rune, the sword was wielded by Viktor for a while before being given to Edge.

the Star Dragon Sword is actually one of the 27 True Runes. It was born into the world with its existence heavily intertwined with the Sun Rune; the two held a strong bond given their respective natures of controlling darkness and light. However, the Night Rune grew annoyed by the dazzling brilliance of the Sun Rune; rather than stay in tandem with it, the Night Rune severed its bonds, transforming itself into sword, and went off on its own.

During its time as a sword, it has become known as a legend, thanks to its effectiveness against vampires such as Aegia and Neclord. During the Toran Liberation War, Viktor awoke the sword from a long nap in order to use it against Neclord; the sword worked perfectly, destroying what was thought to have been the original Neclord. However, during the Dunan Unification War it was revealed this was a double, as the real Neclord appeared in Tinto during this time. Viktor, who had stashed the sword in the Cave of the Wind following the end of the Toran Liberation War, retrieved it, and with the help of Kahn Marley and Sierra Mikain, was able to finish off the vampire for good.
