>That’s a lot of terrain, but it’s most likely in the Tarim Basin, Chinese Kashmir, or Tibet.
It was high in the mountains, nestled in a narrow valley. Though it is a valley of sorts, there is one peak that it is so close, that it could not be more than 2000 feet further up. The lake itself, was somewhat of an assumption, I'm not sure where the body of water was, except that from the boat, the city and peaks were visible. The water then was a filthy rusted brown color, most likely the locals had been shitting in the canal, which flowed to the lake, which likely had no outlet. Whether it really is Tibet or not, I can't truly be sure, but I agree with you on the general region. Another hint could be to find where giant, stone like salamander live within that region. https://en.

>The two aforementioned cities are places where my Self and syncronicity has taken me on vacation in this life already, so I know them to be relative to our past venture
We would likely have passed through those places on our way, at the very least.

The hardest part would be entering the tunnels with a babysitter on us. The odds are also high that this city would be something foreigners are banned from ever seeing or knowing exists.
