The monsters and human reinforcement have been sent. Now, we need to improve the defense of Varadis while also not ignoring the defense of other countries.
Even if it's obvious that they are attacking Varadis, that doesn't mean that all of the cult members were attacking Varadis.
Maybe all of the cult members were informed about the attack to somewhere. So even if they are weak, expert level, advanced level, or even intermediate level mages, if they want to, they can help with the attack. Or if they are smart enough, they can think to attack another location because the main target of the cult's attack, which most members of the cult don't even know.
It was weird that they didn't even notice where they're going until when they entered the portal. But it makes sense if they did it to confuse us in case we managed to infiltrate their rank.
