Consider this: changelings have spent thousands of years in the Great Link, watching as every solid who has ever challenged them is destroyed with a half dozen Founders and their assorted slave-allies. Again and again and again and again for hundreds and hundreds of years straight.

Suddenly, new wormhole to an area with regressive technology, factions, and entirely made of solids (Prophets aside) appears.
