Description: Bruise-leech crawlers, alternatively known as Nelvaan bruise-leech crawlers, were leech-like creatures native to the Outer Rim planet of Nelvaan. Orvos, shaman of Rokrul village on Nelvaan, covered Jedi Knight Anakin Skywalker's chest with bruise-leech crawlers as part of a ritual before sending him off to destroy a nearby Techno Union laboratory. The leeches caused pain as they crawled over Skywalker's torso and left behind blue trails.
Biology and appearance
Native to the Outer Rim world of Nelvaan, bruise-leech crawlers, sometimes referred to as "Nelvaan bruise-leech crawlers," were annelids that were reddish-brown in color, with some having little black patches of fur toward their back ends. They had a circular mouth that was lined with teeth and two protrusions directly behind the head. The crawlers were capable of leaving a blue trail behind them as they moved.
When placed on someone's body, the crawlers could make intricate rectangular designs out of the blue trails they left behind.
In the year 19 BBY, Orvos, the shaman of the Nelvaanian village of Rokrul, used bruise-leech crawlers in a ceremony to prepare the Jedi Knight Anakin Skywalker for his journey to destroy a nearby laboratory operated by the Techno Union that used a siphon generator which had plunged the world into an ice age. The crawlers proceeded to create a rectangular design across Skywalker's torso with the blue trails they left behind as they moved slowly, causing the Jedi much pain.
