One day after the outworlder convention, and one day before Jack escaped from the forcefield cage, there was an announcement inside Eridrus. Edrirus was one of Hydrurond's main cities. This announcement called for every non-army native combatant inside the city to gather at the city square.
These were natives who had levels but were not part of the kingdom faction. Most were adventurers, some worked as bodyguards inside the city, and the rest just worked normal citizen jobs without caring about their levels.
They were confused about the announcement. Some didn't want to comply, but another announcement made them change their minds. The second announcement warned those who didn't comply would be given a penalty. If they left the city, their families would be the ones to suffer the penalty.
