The entire Utopia was in chaos. Whether it was the sudden destruction of the Tomb of the Ancient, the appearance of the Rank Six Mid-Level dragon or the destruction of the Hellgate Fortress and the dragon's successful entry into the Demon Empire, all these events that happened in a short span of time couldn't be ignored by the high-level people of Utopia.
Colon (Rank Five Vampire send by Duke Anderson Bloodworth to catch Evan outside of the Tomb) and others who were waiting outside the Tomb immediately informed their respective factions the moment the Tomb collapsed and the dragon left from there.
After receiving the news that the portal of the Tomb had collapsed and that the people who entered the Tomb were forcefully teleported out, all the high-level factions immediately took action.
Colon and other representatives received orders to bring back their people who had entered the Tomb to their factions before conducting further investigations.
