Bill sighed out loud. Everyone in one way or another expressed their dismay and disappointment. No reinforcements.
They are alone in dealing with the threat, and no one is to blame.
Who can take the fall when the threat is looming everywhere? No one can shoulder the blame without dooming everyone else. Once someone starts pointing fingers, all parties will feel entitled to blame someone else for their shortcomings, if they survive.
The strategists and soldiers began talking about reinforcing the fortress' entrance and setting up traps.
Time was on their side, even as it played against them. No reinforcements, and even if there were one, the guarantee that they would come would be ambiguous, but the short time they have can be used to set traps.
With the direction of the gragas' known, and with a fortress, they can set up traps and force their enemies to take losses even before the fight started.
