From the introduction to Woodland Creatures, the first Chronicle System release:
The Chronicle System is the name we’ve given to the mechanics engine that runs A Song of Ice and Fire Roleplaying. While the rules of this system were designed specifically for George R.R. Martin’s Westeros, they will work just as well for any other setting.
In order to facilitate such game play, we are developing a series of modules under the Chronicle System name, providing new elements and ideas for use with the system that might not always fit into the established world of A Song of Ice and Fire. We feel this will give Narrators more choices and plenty of flexibility to make their games truly their own, whether they are adapting the system to a setting of their own, or simply providing their players with a Westeros that diverges in some way from the accepted canon. Please keep an eye out for new Chronicle System products!
