"Patriarch Zhen Shi! The layer of the Beast Tide has been successfully dismantled by the ranged defenses."
"That's good to hear, but..."
"Several avian beasts had taken it upon themselves to attack our siege engines and archers directly. No casualties yet, but several of our machines have been destroyed."
"May want to check on that former bit soon."
...
[Oh dear. It appears the Whirling Dust Devil Tyrant is smarter than we thought. He sent flyers to cripple our defenses.]
[Figured that would happen.]
[Do we intervene now then?]
[Nay. Let the traps go off first. We don't want to get caught in our own explosives.]
...
SKREEE!
"DIE YOU STUPID BIRDS!"
SWISH!
"Gah!"
"Chip, no!"
"Bastards!"
Thunk, think!
Skree...
As the avian aether beasts kept up with their assault, the defenders found themselves between a rock and a hard place.
Or in this case, a talon and a horde.
