The last part of Toles state was quite mountainous, so Billy wasted some time crossing those parts. While he only crossed the Northeastern part of the barbarians' state, Billy still managed to see a lot of them moving toward the North. They knew that they would be the next targets if the Tersaris state falls, so they couldn't refuse the plea for help from Galatea followers, even despite their numerous differences.
"It seems that even more people than before are coming to help, maybe Svan won't be the only one leading the barbarians this time," Billy thought.
Regardless, while Billy was approaching the temple city, he wondered what he should do. Join the forces there and focus on protecting the city with the troops there or look for Icarus and Lucyna, they probably were nearby. Working with those two would give him more freedom and he won't have to hide most of his skills.
