Mario

Mario is a prisoner in Yew during Ultima V.

Description
Shortly before arrival of the Avatar, Mario had neglected to say that he could only give 40% of his earnings to charity (50% being the law). They tortured him cruelly before putting him in stocks on the town square together with his son Aleyn (for not turning in his father), leaving them to die from starvation.

When the Avatar found him, Mario begged the hero to release him, telling how he'd come into this situation. The Avatar showed Compassion and Justice, jimmying the locks of Mario's and Aleyn's stocks in an unseen moment, allowing them to escape the city.

Ultima V: Lazarus
In Ultima V: Lazarus, Mario had previously been the owner of the Dwarf in a Cask, a pub in Yew that had been one of the main purchasers of wine from Empath Abbey. He had not paid all his taxes when his business hit upon hard times. The Avatar could choose to free Mario and Aleyn by paying their combined fine of 2010gp to Judge Dryden.
