A little bit more info on the map and the statues. The large one with the globe is the sun god (holding the sun). The three in the center are the high saints of the sun faith, while the larger group are statues from legendary and brave warriors.
The main rooms are all sacked, but in the upper right is the secret door which leads to the real tomb, not the fake tomb, that was plundered long ago.

And I have no problem with criticism. As this is the first dungeon in this style, I am open for comments.
