Arknights

When automatons were not yet widespread, these arduous tasks needed many gun-knights working in unison. But nowadays, most of the monotonous, rote duties have been taken up by these machines. While a gun-knight's duties have not changed, the burden has been lightened significantly. There is no longer a need for entire squads to work in concert, and they are no longer required to reside at the foot of the Gate. Buldrokkas'tee is the sole gatekeeper of the modern age. He alone is enough.
