Larian Studios Forums Divinity 2 - Ego Draconis (English) Divinity 2 - Ego Draconis Divinity 3 / Episode 2 [beware of spoilers!]

Well Verdistis isn't in D2:ED AFAIK, and the screenshots were posted by Larian very early during development, so it is hardly a big stretch that they are from a test area.

Also, they were posted 56.5 months ago... with keywords like Verdistis, Aleroth and screenshot, shouldn't you be able to search for it?

I don't care to re-read the Impressing Screenshots topic, but it was mentioned by another forum member not too long after that about it being a test area: More Screenshots. Somewhere between those two posts is something official.
