Iris followed Cane to search through the whole wizard tower with the help of hundreds of royal warriors under Cane's authority. They flipped through all the things within the tower to get information that they needed. And among those people, there were warriors from the Howling Wolf pack as well.
Amidst this mess and their main assignment to find more information on black magic, no one would notice that Cane's warriors were looking for different information entirely, since they knew they wouldn't find anything there.
Iris was not sure what they were looking for, but of course, it would be something that would benefit Cane and add more to his knowledge about the whole palace's affairs. Her head was throbbing painfully because of lack of sleep and worrying over Cane's complicated scheme. She didn't think her brain would be on par with his even when she was in her best condition.
