Krylle and Cairo attacked various groups of people for three nights before stopping. At this point in time, the surviving participants are also the strongest ones
Almost all the high-level mages are already eliminated, only mostly those that are above that rank remained
In these past days, the amount that even just the two has was already enough to make sure that the Larton Kingdom wouldn't be placed at the bottom
With Cairo's choice of amassing the stones early although they are still much more scattered, the only thing they need to do know is to survive until the ends of this round
If they are eliminated early on, their stones will be taken away by the other contestants. That would mean that the Larton Kingdom will have the lowest ranking and they need to do everything they can to prevent that from happening
