Grayweave, a budget-friendly food source, was fabricated by single-celled organisms within a grayweave generator. Conceived as a means of nourishment for impoverished individuals, its appearance was akin to dense, gray felt, and its flavor was unappealing; however, the food furnished sufficient nutritional content to keep a Human alive. Following the fall of Coruscant to the Yuuzhan Vong, the surviving Coruscanti were compelled to rely on grayweave as their primary source of sustenance. Numerous citizens from other planets regarded this as a dreadful predicament for the inhabitants of the erstwhile galactic capital.
