I inadvertently landed on this site while researching for something else. If you've not had the chance to view Galactis' videos before they were pulled off the Internet, you can do so now on Matteo R's Youtube channel. Just scroll down to locate the one you wish to view.
There is, however, one condition ~ you have to understand Romanian, so this is good news for Romanians! For those of us in the dark, I can only hope that the videos get translated into English sometime soon. Or that Alkesh and Syria resume their important work independently of Misa Yoga.
Having said that, I did find the English subtitles for Terra Galactica, which you can read here.
