Before leaving for the vacation, Klaus gave his team a mission to clear all 34 Tier 9 Forbidden Zones, all 6 remaining Badlands, and the various places where some of the most dangerous monsters and beasts are hidden.
Not all of the Tier 10 and 11 monsters and beasts live in forbidden zones; some live on the outside,
However, thanks to Abyss, they managed to locate them, so they were added to the list of threats they would be handling.
Of course, with someone like Skar, Nyxthar, and Veylor leading the mission, their speed was rather quick. It had already been six days into their mission, but they had cleared 8 Tier 9 Forbidden Zones.
The Tier Nine Forbidden Zones they cleared weren't for the faint of heart. They were some of the most dangerous zones they've ever fought in. However, the team wasn't weak either.
Additionally, the reason they were so dangerous was that Klaus instructed them to capture the Tier 9, 10, and 11 monsters and beasts alive.
