On some deep level, Lex knew he was dreaming. But that knowledge did not reflect in any change. He was like a spectator, looking down on himself, but at the same time, feeling all the feelings that his dreamed self was experiencing.
He was being hunted. Something had locked onto him by means he could not understand. It had used something to lock him in place, and prevent him from returning to the Inn. The lock was not actually something that directly blocked him, but something that created an urgent need.
Even at the risk of being discovered, even at the risk of great harm, he could not escape. He needed to reach… he needed to find…
Before the thought could be complete, a familiar pressure he now understood as Dragons Might enveloped him, and a massive yellow eye appeared. Then darkness fell, and the dream transitioned.
The chapter with Lex's dream is chapter 585 if anyone wants to read it again!
