He could hear his pulse thumping in his ears as he ran. Geldauran and Daern'thal and Anaris had suspected nothing as they entered the Eluvian. They had committed so many acts of terror, malice, and spite they deserved to be forgotten. They didn't know he felt that way. Why wouldn't they trust him? They had heard the venom he spewed against Elgar'nan and the others. What they didn't hear was his hatred for their own cruelties. They had no way to know his plans. They stepped through the Eluvian under the assumption that Fen'Harel was going to end the war once and for all and they would be the undisputed masters. At last the others would be out of their way and they would be free to rain pestilence and horror down on those who were weaker.
At least the cruelty of Geldauran and his ilk were at face value. What hypocrites Elgar'nan and the other had been. They may have had good intentions in the beginning, but the power of having lesser beings worship you warped those intentions into a vulgar display of abuses. The people had seen these beautiful creatures, felt their power, saw them create, never age or take ill, and they were awed. They began to worship them as gods. It didn't take long before the benevolence turned to cruelty. The adoration of the people was twisted by these supposed gods into something corrupt. They started looking at those who came to worship them as pets instead of weaker beings that relied on their kindness. They started tattooing their faces to mark which "pet" belonged to whom. They were no longer benevolent leaders but rather spoiled, delusional, and power drunk. They began to fight amongst themselves and Fen'Heral wept at what they had become.
He ran to Mythal. They had talked many times about justice needing to be served and she had agreed to help him with his plan. She had gathered them all at the Eluvian telling them that Fen'Heral had seen something important while walking the Fade that he wanted to share with them. When he arrived, he told them he'd seen a sword with such power that it could end the war and make whoever wielded it the strongest among them. He played on their vanities and selfishness and they all pushed and clawed at each other as they piled into the mirror. He was to be the end of the war that was tearing Elvhenan apart; the only living being in the position to stop both factions.
As he had done before, the foci began to glow and it sealed the Eluvian. He was heartbroken it had come to this. He wept for his brothers and sisters and knew he would miss who they were before their corruption. Fen'Harel was rebelling for the good of the people. They would be so much more without their false gods.
