Lost Woods (A Link to the Past)
The Lost Woods are a set of mist filled woods that cover the top-left corner of the map in A Link to the Past. It's full of thieves, distrustful animals, counterfeit swords, Mushrooms, pitfalls and tunnels. But, most of all, it holds the true Master Sword. Even if Link finds it, he will not be able obtain it until he has all three Pendants of Virtue to prove that he is the Hero of Legend.
"Northwestern Hyrule was heavily wooded. It was dark and dreary, so few people ventured in, but those who did often fell victim to thieves. An old legend retold by the village elders claimed that the Master Sword lay waiting in the woods for one who was worthy of it."
"For as long as most Hyruleans could recall, a dark mist had cloaked the Lost Woods. Thieves found it a fitting place to hide out, but aside from them, the woods were home to animals only. People seeking Mushrooms for medicinal potions sometimes dared enter, but they didn't stay long. Some reported finding swords in the woods."
"When the Master Sword was retrieved, the dark mist suddenly cleared and warm sunshine bathed the woods for the first time in many years."
