Yaschas Massif - 01XAF

This twin location, sans eclipse, will follow a very similar path to 010AF. Speak to your counterpart (Noel or Serah depending on your choice of gameplay) and then head to the Archaeopolis. After the cutscene speak to your companion again and then head up to speak with Hope at the command center. After the collection of cutscenes speak to Hope one more time for a Live Trigger. Talk to your counterpart again and then, after yet another cutscene, you'll get a Live Trigger reward in a box behind Alyssa and Hope. You'll also get the luxury of Chocobos on the map.

After this you'll need to go to the previously blocked off part of the Archaeopolis up the stairs. Use Moogle Hunt to reveal the Mysterious Artefact. Keep an eye out for another hidden sphere containing 600 gil.

Story-wise, there's nothing left to do here except head to the gate at the very south of the map and move forward. However, there are a couple quests you might want to undertake.

Once you're ready to progress activate the gate for a not-so-normal Historia Crux experience. Select The Void Beyond ???AF to move on.

The Void Beyond ???AF

As this location is just a brief stop it doesn't need its own page just yet. After the cut-scenes you can grab the sphere with the Map and then step into the distortion.

Back in the Historia Crux you'll see a new "Locked Location" that you can stop by and accomplish nothing at (seeing as how it's Locked). Instead you'll need to make your way to the Sunleth Waterscape 300AF. If you made a detour there earlier you can hop to it directly from the Historia Crux. If not you'll need to go back to the Bresha Ruins 005AF and use the gate in the western tunnels.
