Overview
Lucifer Rotsac. A tunicate-like animal that ferments decomposing biomatter inside its body. Begins as a larval swimmer but transforms into a spherical adult form. Stops breathing as an adult since fermentation does not require oxygen. Contains isoprene compounds useful for fabricating rubber and lubricant, making it a valuable organic polymer source. Its bioluminescent glow attracts organisms to the surrounding ecosystem. Typically anchored by the Cradle Shootroot, which provides structural support.
