As the Forsaken known as Destroyer of Worlds, Kael wielded immense influence. He now possessed an enhanced connection to the True Power, making him a terrifying channeler, augmented by the abilities from his wishes.
He knew that to truly break the Wheel, he had to corrupt the Dragon Reborn, the one individual who could stand against the Dark One. Rand al'Thor was the key to everything. If Kael could turn him to the Shadow, the Light would have no hope of victory.
He used Moraine, still collared and under his Domination, as his primary instrument. She had been close to Rand, a guide, a mentor, someone he trusted implicitly. Kael forced her to subtly manipulate Rand, to steer him down a path of darkness. He had her plant seeds of doubt in Rand's mind, questioning the motives of his allies, the righteousness of his cause. He had her encourage Rand to embrace his darker impulses, to unleash his anger, to revel in his power.
Rand, already struggling with the immense burden placed upon him, was vulnerable to Moraine's subtle manipulations. He began to withdraw from his friends, his advisors, his lovers. He became increasingly isolated, relying solely on Moraine's counsel. He grew suspicious of everyone around him, seeing enemies where there were none.
Kael, through Moraine, urged Rand to seek out forbidden knowledge, to delve into the darkest secrets of the One Power. He led him to the Choedan Kal, two massive sa'angreal that could amplify a channeler's power to unimaginable levels. He knew that if Rand wielded the Choedan Kal, he could unleash destruction on a scale never before seen. He made Rand believe that this was necessary, that he had to become powerful enough to defeat the Dark One, even if it meant sacrificing everything else.
As Rand's power grew, so did his madness. He became increasingly unpredictable, his emotions swinging wildly from rage to despair. He lashed out at those around him, burning villages, destroying cities, leaving a trail of devastation in his wake. He was becoming a weapon of destruction, just as Kael had planned.
The forces of the Light, scattered and disorganized, were powerless to stop Rand's descent into darkness. They tried to reason with him, to plead with him, but their words fell on deaf ears. Rand saw them as enemies, as obstacles to his ultimate goal. He attacked them without mercy, slaughtering them by the thousands.
The world was teetering on the brink of chaos, and Rand al'Thor, the Dragon Reborn, was leading it towards the abyss. Kael watched with satisfaction as his plans unfolded, as the Wheel of Time spiraled towards its inevitable end.
