The three rings that were hidden away from the Sauron, the dark lord, were found by Frodo. As he was venturing to the elves kingdom, to find the location of the three ring, he saw a cave that was covered in elvish writing. Gandalf had looked at the writings and said that it was ancient and it had not been opened for decades. Gandalf made a spell to open the doors in to the cave. Once the door was opened a foul smell was released, it smelled like corpses. This was a sign for them to back away but Frodo insisted on exploring. As the ventured in to the cave the see a large amount of dead bodies leading to one area. This area had a seal that would not allow anyone to enter. Gandalf used a spell to break it but still the seal stay. Frodo was then sucked in to the the sealed of area because of his ring and he was able to get the ring and leave. They had only two more ring to be collected.
