The Elves vs the Aliens Plus The Doll Makers

Two Stories: The Elves VS the Aliens: The elves, fairies, and other little people have made themselves invisible to mortals for centuries, while living in remote regions of Earth. One day the elves discovered aliens from outer space observing Earth, and learned that they planned to invade. The elves knew that Earth's mortals did not have the means to resist the aliens, so they decided to repel the invasion themselves, using their powerful magic. However they found that their magic might not be enough to fight the highly advanced technology and powerful weapons of the aliens.
The Doll Makers: A couple camping in a remote area of a forest wander into a hidden colony of hostile elves who specialize in capturing mortals and enslaving them. They make dolls in the exact image of their captives and leave them in the forest.
