War of Emperium
Guild sieges on SecondWind RO, the two castles, what a castle pays out, and the seal rewards.
War of Emperium
Guilds fight over castles. Whoever destroys the Emperium and holds the castle when the hour is up owns it until the next siege, and an owned castle pays out every day in between.
Player versus player fighting outside of guild sieges is on PvP Arena.
Schedule from 2 September 2026#
Two rounds every week, each on a different castle. The first siege is on Wednesday 2 September 2026 at 20:00 UTC.
| Day | Time | Castle |
|---|---|---|
| Wednesday | 20:00 to 21:00 UTC | Kriemhild, Prontera |
| Saturday | 12:00 to 13:00 UTC | Neuschwanstein, Aldebaran |
Only the castle scheduled for that day is open. The other one keeps its owner and its treasure, but its Emperium does not appear and it cannot be taken.
Everything under the next heading applies until 2 September.
Until then, sieges are announced#
The stock Tuesday, Thursday and Saturday auto-schedule was switched off on 29 July 2026, so War of Emperium does not currently start on its own.
Sieges are announced instead. Watch the server announcements, the Midgard Herald at , and Discord.
The WoE Sign#
The WoE Sign at shows whether a siege is running, when the next round is, who holds each castle, what it pays, and which items and skills are blocked inside.

Access#
Guild castles are the one exception to the Warper's unlock rule. They are open to everybody from the start.
What else a guild gets is on Guild Services.
Champion Seals from sieges#
From 2 September, three things pay Champion Seals.
| Seals | |
|---|---|
| Hold the castle when the hour is up | 3 |
| Break the Emperium | 5 |
| Take part in the fight | 2 |
The Emperium reward is paid the moment it breaks, so it stands even if you lose the castle again later.
Taking part is measured. The castle is checked every five minutes during the round. Show up for two of those checks and you are counted, and you still get paid if you die and end the round back in town.
The season#
A season is one calendar month. Your guild scores one point for every round it still holds a castle when the hour is up, so both castles count towards the same table.
| Place | Champion Seals |
|---|---|
| 1st | 25 |
| 2nd | 10 |
Seals go to every member who was measured inside a castle that season. Standing in the guild roster is not enough. Collect them at the WoE Sign, which also shows the current standings and past champions.
The first season is September 2026. It starts with the first siege on 2 September and runs to the end of the month, nine rounds in total.
Items and skills blocked inside a castle#
From 2 September, these do not work on castle maps.
| Blocked item | |
|---|---|
| Yggdrasil Berry |
|
| Yggdrasil Seed |
|
 Pumpkin Pie |
|
 Kafra Card |
no storage access during a siege |
Blocked skills are Assumptio, Party Assumptio and High Jump.
A blocked item is not consumed when it fails. You keep it and can use it anywhere else.
