Ermi (planet)

Ermi was a planet. Many years prior to the Clone Wars, a number of Jedi were from Ermi, and were distinguished by crafting lightsabers with multifaceted gems that caused stray energy tendrils to spiral off from their lightsaber blades. During the Clone Wars, distinct equipment inspired by the Jedi of the planet Ermi were available to Jedi Knights.

Behind the scenes
The planet Ermi was mentioned in description of several items available in the Star Wars: Clone Wars Adventures shop. It is possible that the planet Ermi is meant to be linked to the sentient species, the Ermi, mentioned in Xim Week: The Despotica.
