“ A nation was conquered and the conquerers took control and put themselves in all positions of authority. One major problem, the new rulers and the now peasant/ruled class speak entirely different languages.”
“ A race that are always born as twins and only one recieves a soul. The other is soulless therefore without pity, shame, or guilt. The evil race. Can't tell them apart by looking at them.”
“ 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.”
