Gravis was a bit surprised that the Emperor personally escorted him to the Icy Pride Empire. Yet, his reasoning was rather solid. After all, Gravis had just killed an Inquisitor, and no average level five King would be able to keep him at bay if he decided to betray the land beasts.
Gravis didn't have anything against the Emperor escorting them since he didn't decide to betray the land beasts anyway. He had already made his promise, and he would go through with it.
After everything had been dealt with, the Emperor led the squad towards the Icy Pride Empire. Due to the squad's relatively slow speed, they took just as much time to return as they took to get here. Gravis and the Emperor could have finished the journey in a single day, but due to the others, the journey took several days.
