The journey was a tough one, as Veer and his cohort encountered many monsters on their way. It was more so because they were a big group with many strong people on it.
Aurora had made some hypothesis, which told them about the reason for their situation.
She had guessed that monsters were attracted to their Life Force, mana and presence. They were the reason monsters hunted them.
Normally, if they were weak or traveling alone, only weak monsters would come at you because powerful wouldn't be interested in such low quality meal.
However, things changed whenever there was a increase in quantity or quality. Sadly, Veer's group had both so they were bound to attract powerful monsters.
They could have just split up and travelled by keeping some distance between them, but that was also dangerous as Veer wasn't sure he could provide help that quickly.
