Vaarin had talked to Kaizan about his trepidations regarding the blood oath he and the others had taken with Murtagh. Kaizan was already prepared for this part. He had assured him that it was all taken care of. When Vaarin asked about the details, Kaizan had said that it would be revealed tomorrow. He didn't divulge a single detail about how things would happen because as a General, he knew that even walls had ears.
