World Events, also known as Incursions, are large-scale activities that occur periodically at fixed locations in each zone. They are designed to be the most difficult type of overland content, intended for groups of four or more.
There are currently seven types of World Events:
- Abyssal Geysers, found throughout Summerset

Smaller versions of world events designed for solo completion, such as Dark Fissures and Abyssal Pools, can be found as Encounters in some zones.
