We're close to the finish line! Diggy and hid dad found the take-off runway and Itzamna is alive again! There's one last, important thing we must take care of. Talk to Itzamna in the location Tezcatlipoca's Hangouts

We've got two pieces of the calendar - one from that evil Viracocha and the other one from Itzamna's treacherous wife Ixchel. The third one is still missing! Which Aztec god took it? My bet is on Tezcatlipoca. We just have to prove it. Let's search for his favorite hangouts.
In order to get proof, let's find a temple in this area that has an entrance to the mirror realm.

First, place the stones with numbers as follows:

Then, place the rings on the following colored symbols on the ground:

These two mirrors lead to similar areas.

To proceed further, you must make them mirror each other by dragging the stones to the right places.

Enter the teleport and enter the mirrors:

1st crystal skull

2nd crystal skull

3rd crystal skull

Well, knowing what Diggy saw, Itzamna can't be too angry at Tezcatlipoca for imprisoning Quetzalcoatl. I still think he took the last calendar piece! Let's search. Let's hope we find the last piece at Tezcatlipoca's next hangout.

Get the ladder...

...and use it:

You will find a meat roll. Take it...

...and feed the tigers:

Talk to the following guard:

Ugh, I was really hoping you'd find the calendar behind that wall. Let's continue through the jungle, there's a building that belongs to Tezcatlipoca there. In order to proceed, please pull the rope:


Let's search for the building, the calendar piece has to be inside! If not, could it be that we have the wrong suspect? In order to proceed Diggy needs to get the orange key. Please move the stones as follows and you will get the key:

Open the gate and again, in order to proceed, get the red and yellow keys by placing the stones on their correct positions:
Red key

Yellow key

Open the gate and talk to the following character:

All Tezcatlipoca's hangouts just pointed to him actually being a pretty decent guy... That's not good. Who is the final culprit then?! Go talk to him in the City of Gods, he might give us some clues.
