Who knew? Honestly, it took me two runs through this instance for me to nap screens of how awesome Isenguard looked before the fall. Lush gardens, no doubt credit belongs to Treebeard’s influence as he and Saruman conversed occasionally, and pristine grounds.
You could see why Gandalf and the other wizards considered this their headquarters.
The place is a complete opposite of the wasteland it became. But i think that it’s also foreshadowing to what it will become after Treebeard brings Fangorn to reclaim it. But perhaps a little more Wild!
