For a united kingdom

Charles the first of England enlists a boyhood friend to help him convince Scotland's governing body the General Assembly to support a revised version of his father's Book of Common Prayer. The go looking for a reserve Royal Treasury in Scotland to hire a local bodyguard to protect the King while he's in Scotland. They find that the treasury is no longer where it's supposed to be, and go searching for it, as it also holds the Titles and Land Deeds given to the Scottish Barons who had promised to support the King when they were given their Titles and Deeds. Meanwhile the Assembly that had already voted to not support the King has employed a group of Scottish Mercenaries who has just returned from fighting in the Thirty Years War in Europe. They are battle ready and have the horses and weapons needed for combat. Members in the Assembly are afraid if the King gets his hands on the Titles and Deeds that they will lose their Titles and the lands under their control
