“ A rich southern landowner once imported hundreds of thousands of spiders and distributed them along his long, tree-lined road. After a couple of days, when the spiders had make an incredible number of webs amongst the rows of trees, he spread fine gold and silver dust on them to create a spectacular shimmering view. (true story) It was for his daughter's wedding day.”
“ Found written on a torn single page...
'Lay thee patiently and still upon the ground, contemplating the Leper Star in the firmament, 'neath a crescent moon, midst the graves of a boneyard 'til the G'na-Shennu come crawling up from the foetid earth. Fear them not. Let them rage about thee, casting ghoul-dust from their chalky talons and scalps,'til they calm, and so begin to whisper their secrets. Then shall they solemnly withdraw into the earth once more, in peace.'”
“ 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.”
