Calvin Patricius' adopted guardian, who raised him after the death of his parents.

Tristan was Calvin's father's steward, and raised Calvin as his own after his father and mother passed away. Tristan taught Calvin how to negotiate, how to operate a business, and how to navigate the fields of trade, smuggling, and overland transport. Today, Calvin operates a small shop which he lives above in his apartment. He sells food and other basic necessities which the residents of the Artisan's district require in their day-to-day lives. Times are tougher for Calvin than in the past thanks to significantly increased grain prices, which Calvin has refused to pass on to his customers in the form of higher prices.
