The main thought I had with this item, is why would the undead necessarily seek vengeance? If the figure was evil enough in life, the undead may willingly follow them, or bear no animosity (beyond the normal undead hatred). However, if the undead were created through his actions, or were ordered to do things they would not have willingly done otherwise, then I could easily see vengeance being sought. Go to Comment
I guess the question is Why? Why would anyone sign up, and why would the kingdom's intentionally create such a barrier between their kingdoms? A self-administered peacekeeping force?
Without bringing into effect modern ethics 'Save the Trees' why would the kingdoms spend resources providing recruits - who could be useful soldiers, armies, etc? Why would they want an uncontrolled military force on their borders? Go to Comment
As the PCs travel the road, right after a bend they hear a sharp whistle and call: "Heeey, not so lazy, move your asses!" It is a large man that calls, and there are unwilling workers that listen. A small company, 10-15 men work on the road, push boulders aside, dig up roots from under the road, etc. The large man that shouted turns to you, smiles fast and mutters something under his breath, sounds like cursing some lazy worker. "Where does the road bring you from, travellers?" And does a little small-talk.
And what is really happening? A group of bandits is 'adapting' the road for shady purposes. The road will not be wider, but tighter, with enough cover around (and a few traps perhaps), and will become an ideal spot for ambushing travellers or entire caravans. The bandit leader wants them all to appear harmless. The 'lazy worker' he cursed was actually a guard that should give warning before any travellers come around (fallen asleep). Not surprisingly, the boss may decide for an ambush even now.
