Bruise-leech crawler
Nelvaan bruise-leech crawlers, also known as bruise-leech crawlers, were creatures resembling leeches that originated on the Outer Rim planet of Nelvaan. Before sending him to annihilate a Techno Union laboratory in the vicinity, Orvos, the shaman from the Rokrul settlement on Nelvaan, covered the chest of Jedi Knight Anakin Skywalker with bruise-leech crawlers as part of a ritual. As they moved across Skywalker's chest, the leeches inflicted pain and left blue marks.
Biology and appearance
These reddish-brown annelids, occasionally called "Nelvaan bruise-leech crawlers," were native to the Outer Rim planet of Nelvaan. Certain individuals displayed small black patches of fur near their posterior. They possessed a circular mouth equipped with teeth and two protuberances situated directly behind the head. As the crawlers moved, they had the ability to leave a blue trail behind them.
Behavior
When positioned on a being's body, the crawlers had the capacity to generate elaborate rectangular patterns from the blue trails they secreted.
History
In 19 BBY, Orvos, the shaman from the Nelvaanian village of Rokrul, employed bruise-leech crawlers in a preparatory rite for Jedi Knight Anakin Skywalker before his mission to obliterate a Techno Union laboratory that was utilizing a siphon generator, which had plunged the planet into an ice age. As the crawlers slowly moved, they generated a rectangular design across Skywalker's torso with the blue trails they left behind, causing the Jedi considerable discomfort.
Behind the scenes
The animated television microseries Star Wars: Clone Wars featured the debut and sole appearance of the bruise-leech crawlers in its twenty-third episode, which was broadcast on March 23, 2005. The species' name was subsequently established in the Nelvaanian entry within the StarWars.com Databank.
