Eastmost Peninsula

The Eastmost Penninsula is a location from The Legend of Zelda. Located within Level 1, it is the area of the dungeon where the boss, Aquamentus, resides.

When Link speaks with the Old Man found in Level 1, he informs Link that the Triforce Piece he is looking for is found in the Eastmost Penninsula. He does not inform Link, however, that it is guarded by the monstrous dragon, Aquamentus. When Link obtains the Big Key and travels to the Eastmost Penninsula, he finds himself in a room infested by Wallmasters. After Link overcomes the creatures, he unlocks the door that leads to Aquamentus' chamber, where the boss battle ensues. After Link slays the dragon, he obtains a Heart Container and the door leading to the next chamber slides open. Inside, Link obtains his first Triforce Piece, and he is warped to the overworld.

Etymology
The Eastmost Penninsula is likely named after a peninsula, a piece of land that projects into a body of water and is connected with the mainland by an isthmus. Seeing as it is found in the very east and is connected to the dungeon on one side only, this seems likely. If this is the case, it is unknown if the "Penninsula" in Eastmost Penninsula is a spelling error or a purposeful name change.
