Those people from the warrior Association came inside the Draken kingdom. The Draken Kingdom is not associated with the warrior Association but as you know the situation, the warrior Association takes the lead to inform them.
But going inside that Kingdom is not easy. First of all, the kingdom is not located near any other kingdoms. To go there you needed to climb a huge mountain which was almost 10000 feet tall.
After reaching that place, contacting those people from the Draken is also not easy. First of all, compared to any other species, people from the Draken kingdom think of themselves as superior.
It was said that day has the bloodline of dragons which is the reason that they have a superior physique. From birth they are strong compared to any other species.
More than that, people from Draken did not like to interact with people from other kingdoms.
