Does this sentence "as were all things Thanos" means "as if all things were Thanos?" If so, is it common to reverse "were" while omit "if"? Could anyone help with its grammar or structure? Greatly appreciated if more examples could be given, many thanks.
Here is the sentence in the context:
With Spider-Man safely earthbound, Iron Man attached himself to the ship and began using lasers from his gauntlet to cut into the hull. A piece flew out and Tony hoisted himself in. Looking around, it was like nothing he had seen before, yet strangely familiar, as were all things Thanos. Ghosts floating in his mind for six years ever since he first made contact during the climax of the Battle of New York. Pressing a button, his boots activated stealth mode and he silently began to examine the invading ship.
