After the declaration of going south, the last month was spent pushing himself to the utmost limits of his magic and body. Training your magic to just a step before magical exhaustion was dangerous. Doing so multiple times a day, even more so. He did a similar thing with his body, but instead of waiting for his muscles and joints to recover, he simply healed them. The amount of food he ate per day increased manifold. During this month, most of his duties took a step back, and he let Shireen and Lord Manderly deal with them. Things were a bit shaky initially, but they did an admirable job.
