Interestingly, Frodo also saw the ending of the future Middle-earth world on the throne. If Sauron discovers him at this time, he can use his will to control Frodo and take back the ring. He will definitely send an Ring Spirit , without asking any orcs or Saruman to do this.
At the moment Frodo put on the ring, he also heard a sound, and a voice told him to take off the ring. This sound came in time, and he chose to take off the ring again and eventually save the Middle Earth world.
At this time, Aragon is looking for Frodo because he is in danger. Here again, the appearance of the Amon Han throne is mentioned. Chapter 22 of "The Lord of the Rings" is described as follows:
Yargon ran away, intending to catch up with Sam; when the other party rushed into the rowan trees, Yargon happened to catch up with him. Sam was still panting and climbing the hill, shouting Frodo!
"Sam, come with me!" He said, "We can't be alone, there must be conspiracy here, I can feel it. I'm going to the top of the mountain, to the throne of Amonhan, and see what happened. Look! Just like I guessed, Frodo walked here. Come with me, and his eyes were bright!" He said while running wildly on the hillside.
Finally, they finally stopped beside the slope of Mount Amonro, where they found a flat river bank, and after getting ashore, they hid the boat behind the big stones as secretly as possible. Then they carried their backpacks and began to look for a path that would allow them to cross the bare hills of Aimimor to enter the Land of Shadows. Not far away, they also found a big eagle constantly hovering in this area.
This description is very interesting. Later on the same day, while searching for the disappearing Frodo, Aragon followed his footsteps to the top of Amonhan Mountain and also climbed to the waiting chair. But he saw no distant sight, and soon he had to leave the top of the mountain because of the Uruks' raid on the expedition's camp in Pasgaran. Aragon did not try to use the power of this throne. When Aragon sat on that throne, he hoped that a miracle would happen, and he could not see what he wanted to see, because he was not the king of Gondor for the time being. Frodo had such a strong visual feeling because he felt like wearing the Supreme Lord of the Ring. Polomir was then killed in the raid, with Meri and Piping being captured, marking the dissolution of the Ring Expedition.
I think Aragon could have used the magic power of this throne to see what he wanted to see, but his sight was affected by Sauron's confrontation with him and Frodo's power to remove the ring, which Aragon could intuitively feel on the throne. Because a big eagle appeared in his sight. Do you still remember it? Just a few days ago, Aragon, Jimley and Legolas just met Gandalf who turned into a white robe in Fagon Forest .
Legolas once said: I have seen a big eagle circling over our heads in this area. The last time I saw it was four days ago, above the Amon Han.
Gandalf replied: Yes, that's the Eagle King Gewaihir, who rescued me from Orsanqueta, and along the way I saw the Throne of Amon Khan, but it was blocked by the trees in the mountains. I also saw something incredible, now the Lord of the Rings is beyond my cognition, and I have received help from the company sent from Rivendell . This position is easily exposed to the enemy's sight. But Frodo succeeded in escapeing Sauron's control, and I was involved, sitting on the throne, staring at the dark shadows in the distance. I became very tired after that. I was meditating in the dark for a long time.
Gimley said: Do you know Frodo? How do we move forward with him?
Gandalf replied: I can't say it, he has just been freed from a terrible crisis. Many people are standing by his side, and he should go to , Mordor, alone. He has already set out, and that's what I know so far.
