Tyreal Cycle

The Tyreal Cycle (full name: Tyreal Ocillation Cycle) is a 36 year long orbital tide cycle that affects the planet Gotha, home of human civilisation within the Alir System, and subjects it to the gravitational tidal effects of the brown dwarf Tyr and impacts seasonal and climatic conditions on the planet. This cycle has drastically affected the natural environments, geography, cultures and civilisations found on Gotha and the influence of the cycle is particularly felt at higher latitudes where the length and severity of winters can be prolonged or shortened due to Tyreal influences.
