After a week of isolation, most of the town's supplies that had not been destroyed by the Vermins have been used to tend to the injured: this all needs to end soon.
While the last few of your wounded men heal, the rest build up basic defense mechanism in case of another attack, time to set the offensive plan in motion. Your scouts report a small squadron of Undeads coming from the mountains heading this way. You lead your troops to intercept them.
The Undead forces are gaining in strength, if you don't stop all of this soon, it may be too late.
