Firejelly, a combustible and gelatinous material that ignited with extreme ease, served as an organic weapon employed by the Yuuzhan Vong. Typically, this substance was allocated to the Chazrach slave soldiers. Furthermore, it functioned as a tool for torture, whether to extract information from captives or to facilitate the bonding or fusion of various materials.
Following the conclusion of the Yuuzhan Vong War, the Vong transported the firejelly to Zonama Sekot, where it underwent a transformation, reverting to its natural, untamed state and vanishing into the tampasi.
