The husband's party arrived at the dangerous area.
It was an area swarmed by the newly hybrid creations. Those creations came straight from the den of chaos, but in reality, they were the first prototypes created by gods just for the sole purpose of learning the hybrid concept.
Those creatures were made by the goddesses that the elves prayed to.
Their appearances were similar to Hana's training dummies, but those creations were thinner and taller. They also had much more menacing aura swimming around them.
All of this summed up to one thing; kill us! Those monsters basically reeked off with such feelings around them and urged every elf to destroy them.
By destroying them, the elf would get an orb similar to what Josef and Maria used to get an hybrid concept.
Of course, as per the elven queen's orders, the elves hadn't touched these concepts at all.
