The Star Dragon Sword is an incarnation of the Night Rune that resided in the Cave of the Past at Qlon Temple. It had a face carved into its hilt which allowed it to talk. It is one of the few weapons that can kill supposedly immortal demons, such as vampires. The sword was very prideful and prone to nagging and it was also large, making it difficult to handle by an ordinary warrior.

When Viktor and the leader of the Toran Liberation Army travelled to the Cave of the Past, they came upon the Star Dragon Sword. When the sword learned that Viktor aimed to kill Neclord, the Star Dragon Sword decided to join them. Wielding the Star Dragon Sword, Viktor was able to defeat and ostensibly destroy Neclord, as the Star Dragon Sword was an incarnation of the Night Rune and Neclord was merely a servant of the darkness.

For the rest of the Gate Rune War, the Star Dragon Sword remained with Viktor. Following the end of the war, the Star Dragon Sword was presumed missing, alongside Viktor.

"If I don't thump an enemy hard enough, he won't go down. It's your fault! Your fault!!!"

- Viktor

Following the Gate Rune War, Viktor had brought the sword to Jowston before abandoning it in the Cave of the Wind, finally tiring of its bickering.

Once Neclord reappeared, however, Viktor reluctantly returned to the Cave of the Wind with Kahn Marley and the leader of the New State Army to retrieve it. Enraged at having been abandoned, the Star Dragon Sword attacked the group but was subdued and agreed to be used again after Viktor groveled for it.

Following the Dunan Unification War, Viktor continued to travel with the sword for a time.

Trivia

 * The Star Dragon Sword's name would be more properly translated as the Zodiac Sword. The Star Dragon Sword gained its name through Konami's translation of Suikoden, when they translated the kanji making up the name of the Star Dragon Sword/Zodiac Sword individually - thus 星辰剣 became Star (星) Dragon (辰) and Sword(剣), rather than Zodiac sword. The name Zodiac Sword remains popular in the fan community, however, and was used in the fan translations of Suikogaiden Vol.1 and Vol.2.
