After Edgar's defeat, the Hero's Party has been banished forever by Horizon's citizens (who refused to provide provisions for them) because the Party refused to help of defeating the demonic Edgar and deeming Arios and his teammates to be cowards when they believe they would defeat the Demon Lord. Horizon now idolized The Shrouds as their heroes and given Rein Shroud and his companions any source of provision they've wanted even given Rein and his companions any items for free.
