The Ancient Ruins of Hosszú Bányázait Alagút Episode 6

Yotsuya's party has saved the people who were under attack by kobolds. They then find out the group is a squad of soldiers from the dictatorial Kingdom of Deokk, and they're escorting heretics to Radodorbo to be executed. The party still isn't sure how they should interpret their quest, so for the time being, they accompany the soldiers and heretics on the way to Radodorbo.
