Act as a master worldbuilder with expertise in dark fantasy and speculative biology. Craft a detailed setting where the deceased are encased in amber-like resin, preserving them indefinitely. Describe the [CULTURE] that reveres these preserved dead, the [ECOSYSTEM] that produces the amber substance, and the [TECHNOLOGY/MAGIC] used to harvest and shape it. How does this practice affect societal structures, religion, and daily life? Are there forbidden uses of the amber? Explore the consequences of a world where death is not an end but a frozen continuation.
