Even though the Gods struggle so, their achievements are temporary at best.
For all beings must dream, and within those dreams dwell the Dreamer.
Come then and succumb to the lord, come then and enter the realm of sleep.
Come then taste the nectar, made of the tears of the dreamer.
-The 5th verse in the Book of the Dreaming Cult
On a location with numerous webs, and at least one big spider, there is a something inside a cocoon. It is humanoid in shape, still moving. If the heroes free it (not before they kill or drive away the spiders), they meet a ... zombie!
The poor zombie wandered the dungeon alone, and tried to kill a big living creature (= a spider). The spider used the usual treatment, even if this victim did not look tasty. The zombie can be easily killed as any other zombie. It got but several doses of spider-poison, so can be something worth if it is extracted. You can mention to a druid or ranger the fact the spider had no poison anymore.
