While the Elves Island and some of the first envoys from the Divine Continent could not enter the North Sea, the situation in Dry City was somewhat tense.
The local government had been one of the first to notice signs of the detonation of Minos' Black Hole Bomb weeks ago. Hence, the government and the Stuart family knew their leader had recently fought.
Minos' soul signal was still active, but no one knew what his situation was. He could be from fine, investigating his enemies and the core of the North Sea, to be held hostage by his enemies or seriously injured.
There was no way of knowing his situation, but it was a fact that he was alive, along with Ruth, while several of his party had died.
Before leaving for the North Sea, Minos' companions had left items with his vital signs so that the imperial government would have an idea of what was going on.
