Dwarves all liked excavating enormous spaces inside mountains, then building houses from the readily available stone or carving homes into the rock walls.
Aerie Peak was likewise an underground city within a mountain.
They had not gone too far when hollowing out the mountain for this city.
Thick outer walls remained, allowing it to completely disregard the threat of Red Dragons.
Although the Red Dragons' Dragonfire was formidable, burning through rock at least a hundred meters thick was beyond it.
Besides its strong passive defenses, its active defenses were also formidable.
If Red Dragons dared come too close, the Wildhammer Dwarves' anti-aircraft guns would surely blast them to death.
Dragonfire had a range of a hundred meters at most, while anti-aircraft guns could effectively penetrate dragon scales from four or five kilometers away.
Sending Red Dragons into a head-on fight against anti-aircraft guns would get them killed in no time!
Armor-piercing shells carrying terrifying kinetic energy would punch through their tough scales and tear them into rag dolls.
Even when flying past Aerie Peak, they had to give it as wide a berth as possible.
Who knew whether anti-aircraft guns lay in wait inside those fortresses carved into the nearby mountains?
No Orcs Handler would let a Red Dragon approach this city.
And Aerie Peak's Gryphon Riders were no pushovers either.
Recently, several Red Dragons passing through had been surrounded and killed by Gryphon Riders, one after another.
The Gryphon Riders would fly over and unleash a fierce assault, then return to Aerie Peak when they tired, and you would not even dare pursue them.
So when their own numbers were insufficient, it was best to avoid provoking these fellows if they could.
The Orcs Handlers believed that once they gathered enough Red Dragons, they could wipe out the enemy
