The hole was called Skywell in Qin. In Cloudflow, it was called Collapsed Earth.
Saleen and the others ventured into the Skywell cautiously. They found that the place had few dangers when they descended slowly along the edges.
Magic beasts found within the Skywell were all small, the largest little more than a meter long. There were not many puddles inside the Skywell, which meant that there were underground rivers drawing rainwater away.
Saleen began using astrology for calculations after the magic compass was rendered useless. While the starlight above could hardly be seen even at night, Saleen's Elemental Eye allowed him to clearly see the power of the stars amidst the clouds, reaching the bottom of the Skywell.
The starlight showed him the way. While Saleen's level nine astrology was not that powerful, he was able to roughly deduce where the entrance to the temple was.
