The Golden Membranes are organic, mucous-like structures found in cave passages. They resemble a golden webbing, firm yet stretchy, and contain traces of Splendor magic. The membranes absorb and saturate the surrounding area with Splendor energy, impacting both the environment and local goblinoids.
Sylvie tested the membranes and found they adhere to surfaces without being harmed by flames. She applied a piece of the membrane onto a flaming skull, which remained unaffected. The membranes are stable and do not obstruct movement, allowing for easy navigation through them.
