There were multiple complex paths in that huge cave. The black fog in the cave had already dispersed, but the paths were still filled with the black fog. Therefore, Irina could only use the Holy Light to form a protective shield over everyone, and continue going deep into the cave based on her instinctual perception of the source of the black fog.
Everyone moved very quickly. Around 15 minutes later, Irina stopped. The Holy Light shield shattered and dispersed the black fog on the path, revealing the huge stone door at the end of the path.
The black stone door was a good 100 meters tall, and there seemed to be a huge mural carved on it.
Krassu made three fireballs and maneuvered them close to the stone door so that everyone could see the mural carved on the stone door clearly.
"What?!"
Everyone was shocked.
