A considerable Tax was one of the included adventures in our June 2020 Digital Gaming Subscription.
In this scenario the party will encounter a young wizard called Wilhiam who was sent to a small town to audit the townships back taxes for the local regent. During this audit in the basement of the mayoral building he and his partner Rold found a shimmering silver door with a single eye upon it. Wilhiam left to ask someone about it and when he returned Rold had vanished. (CR 5-7)
