Gimer-gum

Gimer-gum was a substance that shared its name with the gimer stick, a cane used by Jedi Grand Master Yoda. While Jedi Master Douglas Sunvale, Jedi Knight Vernestra Rwoh, and the scientist Avon Starros were stationed at the outpost Port Haileap on the Outer Rim planet Haileap during the High Republic Era, Sunvale often told Rwoh that Starros was a genius and that if anyone could solve a problem with only gimer-gum and a few bits of wire, then it was her.

In 232 BBY, Sunvale was killed in an attack by the Nihil pirates, and Rwoh and Starros were among a group stranded on the Outer Rim moon Wevo. While on Wevo, Rwoh realized that she had underestimated the scientist who she had viewed as a gifted child, noting that Starros was more "brilliant" than she and others had known. The Jedi Knight then mentally noted that Sunvale had been aware of the scientist's intelligence, and recalled his statement about Starros and gimer-gum.
