World events

The world has 64 event zones. When you walk into one, the game rolls for an event, and it rolls again every 15 seconds while you stay inside.

Each zone has a list of outcomes with weights. First the game removes the outcomes whose conditions do not hold: a quest you must have finished, a world state, or another event that must be running. Then it draws from the weights that are left.

"No event" is an outcome of its own in 44 zones. When it comes up, or when nothing is left to draw, the zone waits its cooldown before it rolls again.

Most zones wait 30 minutes. While its event runs, a zone does nothing. After the event ends, the zone waits its cooldown again (30 minutes if it has none), and the same event cannot start from any zone for at least 30 minutes.

Zones with the same name in the game files share one cooldown.

In 9 zones the weights add up to less than 100. This leaves no room for a "no event" roll, because the draw uses only the listed weights.

Sleeping until morning shortens every cooldown by the game time you skip, times 0.389.

Cooldowns are not saved. When the world starts again, every cooldown is cleared.

The world also has 17 fixed event spots. Walking into one starts its event at once, with no roll and no cooldown, unless the event already runs or was a one-time event that is done.
