"Spirit Altar" 

These elite guilds might also have connections with domain masters with the same profession as the guilds, but the irregular tamer didn't even have one...

The first ancestor had a domain, so he was also a domain master.

Ainsley was in deep thoughts, but soon, the group entered the vast underground hall. 

Unlike the hall of some gorgeous palaces that Ainsley saw in movies and castles of royal families before, this hall looked a bit simple, yet it still had a sense of low-key luxury. 

As usual, the wall of the entire hall was still the primitive rocks and soil from the mountain, but maybe because the mountain itself was unusual, these rocks and soil were also unusual. 

The rocks and soil all glowed in blue light, just like something that was dyed with a special paint that could glow in the dark.
