Fortunes of War - Real, or illusion?

[cereal]

When you start the level in the keep, the normal bridge effect is used, and the exit is also a normal bridge, unlike the illusion bridges for the other three maps. This in a sense implies it's a real place, like the Helmgart levels. Yet, the portraits and three previous levels imply otherwise. Simply put, my question is, is Fortunes of War the true return to the true Ubersreik, and not an illusion masquerading as Ubersreik, or is it some sort of meta thing and it's an illusion?

I believe it isnt an illusion because of vt1's town meeting which is the same as fortunes of war but there is very specific changes to how it looks. It is now a lot more destroyed than before thus hinting that it isnt go back to the same level and instead going back to ubershreik after the events of vt1.

It's real. You go into the illusions of the first 3 maps to find the runes so you can get the very real treasure out of fortunes. That's the story of the DLC.

If you queue up for one of the first 3 Ubersreik maps, the portal shows a shimmering cicrle effect. If you queue up for Fortunes of War (or any other "real" map), it's a magical bubble.
