The "Spring Without Sun" is the nickname the small folk gave the Spring that began in 502AC and lasted for two years.
An unusually wet and stormy Spring brought a certain amount of chaos to the realm from 502 - 504AC.
Lots of rainfall meant swollen rivers, floods, and bridges that were swept away. Mass flooding across the continent brought disorder, making the Riverlands essentially uncrossable and even harder to live in than they had been. Refugees flocked to major walled cities and castles where disease spread rampant. Most major mountain passes (Prince's Pass, High Road) became blocked off and flooded, and while rain is good for crops, too much rain caused fields to be swept away and harvests ruined.
- The Gold Road bridge across the Blackwater rush was swept away by the swollen river.
- The bridge at Fairmarket was swept away by floods.
- At Riverrun, the point where the Tumblestone and the Red Fork meet became a lake, making entries and exits difficult.
- All rivers and waterways were swollen throughout the Riverlands, Westerlands, Crownlands, Stormlands, the low lands of the Vale, the Neck, and the upper areas of the Reach.
- The North was experiencing high amounts of snow.
- The Riverlands, Westerlands, Stormlands, and Crownlands were experiencing loss of crops, flooding, and refugees massing in the main towns (Lannisport, King’s Landing, Harrenhall)
- The bloody flux was spotted among the smallfolk.
- Due to storms increasing, shipwrecks became more commonplace and the already violent currents that surrounded the Iron Islands were even stormier and made travel by sea more dangerous, even for experienced sailors.
- Some mines in the West collapsed, temporarily halting the production of gold and silver.
- Dorne and Essos remained mainly unaffected.
