Eastern Palace (A Link to the Past)

The Eastern Palace, called the East Palace in the GBA remake, is the second dungeon in A Link to the Past. Link enters the palace as part of Sahasrahla's test to see if Link can overcome the palace and obtain the Pendant of Courage.

Entrance to the Palace
As suggested by the name, it's found in the eastern side of Hyrule, inside a rocky canyon.

Themes and Navigation
The dungeon's puzzles and obstacles aren't too complex, and are generic in nature. In some rooms, there are boulders rolling, with some of them being bigger than others; in those parts, Link must walk very carefully and get out of the way when a rock is approaching. The main treasure item is the Bow, which is located near the center of the dungeon in a large room filled with Stalfos. At the end of the dungeon, Link must fight six Armos Knights for the Pendant of Courage and an obligatory-to-seize Heart Container (in fact, all Containers are). Upon besting the palace, Sahasrahla will explain more about the Master Sword and the Knights of Hyrule, and will encourage Link to find the remaining pendants so that the Blade of the Evil's Bane can be claimed (the pendants' locations will be marked on the map as well). He also gives Link the Pegasus Boots.

The Eastern Palace returns in Four Swords Adventures as the Eastern Temple.

A Link to the Past comic
In the A Link to the Past comic, Link travels to the Eastern Palace after being told by Sahasrahla's Friend where Sahasrahla can be found. There, he finds the descendant of the wise men, and although he is  puzzled as to how someone so young like Link could be searching for the  Master Sword, he tells Link he must recover the Pendants of Virtue   to claim the legendary weapon. Sahasrahla reveals that he can help Link  by giving him the Pendant of Courage, but since the task to  finding the  remaining two pendants will not be an easy one, he asks  whether he will  be able to accomplish said task, to which the young hero confidently says yes both for Zelda and his deceased uncle. Just as Sahasrahla hands the Pendant of Courage to Link, the Castle Soldiers  pursuing Link find him. Empowered by the pendant, he easily dispatches  their leader and sends the rest fleeing. The young hero, amazed at the  power of the pendant, promises to find the remaining two pendants and leaves the palace to search for them.
