The Ceremonial Hall

Hao Ren had no idea what the Thirteen Sages had released and what ritual they held. But something was inevitable: when Hasse brought back news of the Sin of the Divine Blood from the Ancattero territory, the sages freaked out. They must have known about this sin or at least had some prior understanding of it. That was why they took action hastily. They found a sacred relic from the ancient ruins of Coldpath and activated it in the ritual. But the ceremony had unexpectedly awakened a "monster" from its nightmare and "infected" the entire garrison of the Coldpath dimension without warning.
