I am running a D&D campaign, in which my players are helping a village on the edge of a large empire. The empire has just won a war against a Daemon race and they are busy restoring order to the Central parts of the Empire. My players had a task to destroy a Hobgoblin Fortress but they demanded they go to the Capital and request help from the Marshal. I agreed in the end, but now I need a justification why the Marshal would spare any troops helping a village that has no strategic value against an enemy that is not the priority.
Clarification Edit: The Lord is going to give them One Holy Crusader, an elite warrior, "2nd Class" (Assuming Normal Peasant conscripts are 5th class and archangels are 1st Class). But I need a reason for him to do this. (Examples Ive thought of are: Goblins can escalate to Daemon-Spawn if they worship Daemons, Being Bribed etc). So answers can include extra quests to do for the Lord (If you get my best Guard to stop drinking then I will let you have him) or rationalisation of protecting a useless border town.
