This would be a fantasy setting.
The Western borders of the kingdom of Vanriel have been plagued by Orc attacks.
The Orcs had not been seen for many generations, but now they grow bolder with each new season.
As one of the measures to protect the Western outskirts of his Kingdom, King Berathar the III has decided to garrison some of the old, disused forts that are still found all along the Western border.
These forts were built three hundred years earlier, during another time of Orc aggression.
In this setting, both men and women would serve in the army, so male and female soldiers would be allowed.
Recruitment of new soldiers has only just begun, so the garrisons are rather small in the early days.
The outpost in this game would be held by two dozen men, led by a captain.
The players would assume the roles of either a soldier garrisoned at the old fort, or a villager who lives nearby the fort.
The first section of the game would deal with the day to day proceedings at the fort, the second part would then cover an actual Orc attack where the defenders are faced with overwhelming odds.
I would keep the level of magic limited. I am willing to allow the presence of one Mage, either at the garrison or in the fort.
I would use the RPG Skyrim as the basis for the weaponry/armor in this game.
Whomever has an interest to play this game, feel free to express it in here.
If and when I have enough people, I would add a character sheet to the opening post.
