Ironclaw

Ironclaw is a series of tabletop role-playing games created by Jason Holmgren of Sanguine Games, and features anthropomorphic characters in a setting inspired by class and religious conflicts during the Italian Renaissance. "Jadeclaw" is a related game in a concurrent East Asian setting.
Publication history.
The first edition of "Ironclaw" was published in 1999 by independent publisher Sanguine Games. In May 2002 it was voted the most-popular furry RPG in a public poll which included works of the same era such as "World Tree" and "Furry Pirates". The second edition was published in 2010; it has since sold over 10,000 copies.
As of 2019, the game has been in continuous publication, with various add-on books such as "The Book of Monsters" featuring Ursula Vernon, and is run at furry conventions such as Furry Fiesta, Midwest FurFest and Anthrocon.
System.
"Ironclaw" uses a system where attributes of characters are matched to different polyhedral dice. These attributes include a character's physical, mental, and social capabilities, in addition to the abilities associated with their species. This system was later used in Sanguine's other role-playing games, including "Jadeclaw".
