SKR abbreviation for: Small Kingdoms Reckoning
The starting point for this dating system is the signing of the Treaty of North Hoarbrite. This was the treaty that Drillian, Blackwater and Gold Hills signed as a show of solidarity against any incursions by Terraguard. Later Jarvis was added to the treaty. Jarvis has a little used calendar dating that starts at that point, SKR +210, however most people continue to use the Small Kingdoms Reckoning to this day.
