The true situation of the Brass Fortress is evidently much worse than the outside world imagines.
When the subspace power, which isolates communications and shapes mazes, emerged, the fortress had already been under attack, nearly synchronously with the worst stage of the war at Blackflame Mountain Pass.
Should all this be orchestrated by Twilight, then those heretics are aiming for a double-front victory this time.
Almost the moment the masking fog fell, a massive number of Ratmen launched an "underground raid" on the Brass Fortress and its surrounding strongholds. These bastards seemed to have long confirmed that the Brass Dwarves would lose the protection of Mother Earth, making their assault madly bold and straightforward.
Lacking the tactical cover like at Blackflame Mountain Pass, they decisively struck when the fortress was shrouded and isolated.
