The GM:
I have decided that the Tyrant is a man whose public title is the Lord Governor. His name is Horace Blackgreve. His allegiance to Calum, the would-be goddess of fear, death, and blood, is not at all publicly known.
Time for a Raid, folks... I would suggest a furniture warehouse, or something, since you need stuff for your Barracks...
...But since you have no helpers, better to steal a shipment of stuff like that... something that's already packed up and on wheels, that could be redirected toward The Sandstone...
But that sounds kinda bulky... maybe it's better you just get started on your Hoard, so you can just buy what you need... So what'll it be...? Money? Jewels? Something else that you could use to turn into liquid assets...? Kidnapping one of the Tyrant's head tax collectors and holding him for ransom, maybe...?
