A few days later...
Vicente and Layla reached the border of the Seidel Kingdom and the Chutha Dynasty, having slowed down hours ago to find the ruins of The Skull City.
The Skull City was not a hidden place that only a few knew about. Great powers within and outside the kingdom knew of its existence, which occasionally resulted in subordinates and members of large groups moving to the ruins.
What would happen if a specialist discovered a place like the current destination of Vicente and Layla? There were two options. The first was to try to explore and collect the resources for themselves. The second, usually associated with stronger people finding lower-level things, was to show their powers of the possibilities in such a place.
That's what a Sovereign or a Paragon would do when they came across places like The Skull City: give the opportunity to weaker juniors or subordinates.
