Ezekiel had a lead on the rest of Devon's followers near the kingdom of Zion. He didn't inform Katelina about this since he didn't want to add to her worries. She already had enough on her plate after the incident of the stolen dragon eggs and Priest Mauro's betrayal.
Also, he could deal with this one witch alone. He knew where she was located because he had seen it from Priest Saul's memories. However, Priest Saul had managed to block him from accessing other crucial memories in his dying moments. As a result, Ezekiel was unable to discover the locations of the rest of Devon's followers.
Ezekiel soared into the night sky, his dragon eyes sharp and focused. The cold wind rushed past him as he flew toward the southern part of Zion. He knew that the witch he was hunting was one of Devon's most dangerous followers. Eliminating her would be a significant step in dismantling their plans.
