[i]The Didact's personal warship, the [/i]Mantle's Approach, [i]is more than 350 kilometers long. It's around the same size as the first Death Star. Fortress-class warships are 100 kilometers long. They dwarf every single ship in the Star Wars galaxy on a hilarious scale. And as I've said, the Forerunners are capable of hiding their ships in Slipspace, which Star Wars ships do not have the ability to enter, and attacking the Star Wars galaxy from there. Slipspace and Hyperspace are two very different things with different sets of rules. There is literally no way for the Star Wars galaxy to match the might of the Forerunner Ecumene. They can't get into Slipspace, so they have no way to fight back. Meanwhile, the Forerunners are inducing supernovae in all of the important star systems throughout the Star Wars galaxy, and no Star Wars faction has any means of stopping them. It's a curbstomp in favor of the Forerunners.[/i]
