In order to make some additional money to prepare for their final confrontation with the Doge, the mercenary companions have taken on the seemingly simple job of delivering a scroll to an eccentric old man.
“Dear sirs, I kindly ask that you bring this ancient scroll to my friend Leonardo. It is a precious document and many spiteful persons
would love to get their hands on it; it is a formulary allowing the creation of a marvel from times gone by.”
Andrea Del Verrocchio.
The heroes know they would not have been hired for the job if it was going to be a simple delivery, so they prepare themselves for trouble. Just before reaching their destination, they run into the trouble they were expecting.
