Nedra awoke in her cottage after making the cage for Zagan in his castle room. She didn't know how much longer she could keep doing things like this for him.
What Zagan didn't realize or didn't care to realize was that this portal world she had created for him was something that continually sapped her energy. It was not like all of the other things she did—creating cuffs for the alyko, creating the containment facility with its unique wings that reflect nature's elements, creating the cage in that room—that were relatively minor. With those smaller tasks, she could make them, leave them to exist in the way that they were intended, and they did not continue to draw energy from her.
