As you travel through the thick growth of a forest, a great shadow suddenly moves over you. You raise your head fast, but whatever it was, it was faster. However you try, you don't see anything, and nothing approaches you. Maybe it is better so.
Elves use nature as strength and borrow from the trees to keep them living. An elf out of the forest for more than a day begins to die and within 3 days is dead without borrowing the strength of nature.
