In short, the Imperial Army advancing toward the Southern Heavenly Gate really was using the legendary "space age ram tactic."
Half a year earlier, they had already gathered a large number of engineering units at Dawn Pass. Naturally, they had been preparing to build a fortress there again. Fortresses were indispensable at important thoroughfares like this.
They had also wanted to see if Unity Fortress could be repaired.
But the truth was, this ancient space city, passed down from billions of years ago, had fused with the outer asteroid structure used to camouflage it. It had become an enormous, irregular lump more than thirty kilometers in diameter and weighing over forty trillion tons, made up of all kinds of superalloys.

Even judged by its appearance alone, it was more than four times the size of the largest Skyforts belonging to the Empire and the Alliance.
