Treasure Islands
Somewhere in the archipelago, the tide leaves behind more than driftwood. Every few hours a handful of uninhabited shores glint with a faint, golden shimmer, a signal to sharp-eyed Governors that something has washed up beneath the sand.
Chart & Navigation
Reports & DispatchesWhat They Are
A treasure island is an ordinary uninhabited shore that the archipelago has, for a time, marked as holding something worth finding. You will see them in region view as islands that twinkle softly. No other indicator, no label, no fanfare. Just the shimmer.
- Only uninhabited islands can bear treasure. A settled shore cannot sparkle.
- The set rotates roughly every 4 hours. The same island may or may not be chosen again.
- The number of treasure islands scales with how busy the world is. A thriving archipelago shows more; a quiet one shows at least a couple.
Claiming the Shimmer
Send a raid fleet to a sparkling shore. If your raid lands successfully and a landing force survives the wild defenders, the island's prize is yours. The shimmer fades the moment it is claimed. Other Governors who arrive afterwards will find an ordinary, picked-over shore.
The prize itself is not guaranteed to be friendly. Most successful claims yield a buried treasure chest worth between 5,000 and 10,000 coins (90% of claims). A smaller share (10%) uncovers a cursed chest. The landing force is lost, but your ships escape unharmed. A minority of claims turn up nothing but sand. Either way, the shimmer is gone.
Why Rotation
Before the rotation existed, any raid on any uninhabited island could stumble into a chest by pure luck. Now the archipelago itself decides where a prize lies: briefly, visibly, and for everyone to see. Speed, scouting, and fleet readiness matter more than repetition.
Read the Charts Faster
Sweeping the map for a shimmer takes time. Chart-readers need a beat to take their bearings between regions. The Laboratory on your capital island shortens that beat: every level cuts the scouting delay on the world chart. Rivals with a neglected Laboratory will see a shimmer fade before their charts settle, while a well-appointed laboratory lets you leap from region to region almost without pause.
Strategy
- Watch the map. Open region view periodically. The shimmer is your only tell.
- Send cheap landing troops. A cursed chest wipes the landing force regardless of what you sent. Spearfighters die just as surely as stone throwers, at far greater cost.
- Don't linger. The rotation is short. A fleet that arrives after the claim finds nothing but an ordinary shore.
- Spread your raids. Multiple islands sparkle at once. The quickest hand to any one of them takes the gold.

What are the treasure outcomes?coins, curse, or sand
A successful claim usually checks three outcomes: a coin chest between 5,000 and 10,000, a cursed chest that destroys the landing force, or no prize beyond consuming the shimmer.
The current world gives coin chests a 90% claim chance and cursed chests a 10% claim chance.
Common questions
Can a settled island hold treasure?
No. Only uninhabited islands can shimmer, and the marker disappears after a successful claim.
Does every successful landing find coins?
No. Most claims find coins, a smaller share open a cursed chest, and some turn up nothing. The shimmer is consumed either way.
What makes treasure hunting faster?
A prepared raid fleet matters first. A higher Laboratory on the capital also shortens the chart-reading delay between regions.
