This is the link to their channel. A month or two after they do a podcast/release the audio on youtube, they make a video production of it. They're beautiful, too. Makes them worth a 2nd watch when the video comes out.

Click on the Fall of Civilizations playlist, those are all the videos. The chronological one is nice, they place the civilizations in chronological order
