I made a temporary version of this mod for the Definitive Edition using the method in a Reddit post, while we're waiting on a DE version from the actual author. Here's a link to the .pak file.

Drop it into your "<Documents>\Larian Studios\Divinity Original Sin 2 Definitive Edition\Mods" folder, then enable it in the Mods menu in the game's main menu.

You may need to mess with the mod load order (though I didn't). If done correctly, as soon as you go up the stairs from the tutorial deck after starting a new game, you'll see all 4 pyramids sitting in a row on the floor nearby.

Original mod rules and restrictions apply, results may vary, I am not responsible for any problems this may cause, use at your own risk, etc. Have fun!
