Rune of Night (Star Dragon Sword)

History
The Rune of Night (or Night Rune) is one of the 27 True Runes. It has transformed itself into a powerful talking sword called the Star Dragon Sword. It is also sometimes referred to as the Zodiac Sword. This weapon, being a True Rune, is able to cut through just about anything. Even, able to break the bonds of other Runes.

Because it governs the forces of the night, nearly all creatures of the darkness are subjugated to its awesome power and influence. As such, this sword is perfect for slaying vampires, zombies, and other undead creatures. The vampire Neclord being the most famous example.

Originally, the Rune of Night was bonded to the Sun Rune, but annoyed by the luminous sunlight transformed itself into a peerless blade to break those bonds. The Dawn Rune and Twilight Runes were birthed from those shards.

It is unknown if the sword grants its wielder the benefits of a True Rune, such as immunity to sickness and immortality. However, it is said the Zodiac Sword never rusts or wears out. So, at least some benefits of the Night Rune seem to be embedded in the metal. Lastly, the True Rune seems to have a past association with both Sierra and Zerase.

The current user of the Star Dragon Sword is Edge. The most notable previous user is Viktor.
