Greetings, Admiral
This is the Rise of Stars.
 
We would like to give some information about the ROS Galaxy & Sector Archive

Please check the content below.
 

■ Galaxy

1) Galaxy
  - Galaxy is similar to the game server that admirals generally know.
  There are numerous sectors within the ROS galaxy. (ex. Galaxy 1, Sector 1 ~ 8)

※ The image is not a final product, and it may differ from the actual service.
※ The figures in the image is a random number, and it does not show any actual Silther Particle information.

2) Galaxy and Silther Particle
 - There are limited number of Silther Particles within the Galaxy, and are shared by all sectors in the galaxy unlike other available resources. 
Meaning, the faster you mine, the more Silther Particles you can get compared to other sectors in the galaxy.
However, the exchange rate between the Silthereum and  Silther Particle may vary depending on the total amount of Silther Particle mined in the Galaxy.

3) Galaxy Lifespan (Galaxy Council, Sector Reposition)
 - The Galaxy lifespan is determined by the % of the remaining Silther Particles in the Galaxy.
When 90% of available Silther Particles are mined, Galaxy Council Battle begins.
It will be held in all sectors in the Galaxy, and the ranking will be calculated based on the Galaxy (not by each Sector).
When the Galaxy Council Battle ends, all admirals will be teleported to a random sector and position.
During this repositioning, some information from the previous sectors may be lost.

※ The details may change in the future

■ Sector Archive

 1) Sector Archive
 - Sector Archive is a non-module where admirals can check the Sector’s history and opening requirements for various contents.
Admirals can open a specific content by completing missions displayed within the Sector Archive, unlock higher level contents, and collect related rewards. 
Simply put, the Sector Archive show the growth of the Sector and how mature the Sector is.

※ The image is not a final product, and it may differ from the actual service.

2) Opening Resource With Sector Archive
 - The resource planets are distributed among 5 zones of the Sector. As you get closer to the council, higher level resource planets will be available.
Most zones are closed when the sector is opened, only level 1 and 2 resource planets will appear at the outer boundary of the sector.

From then on, additional zones will open through the Sector Archive, and with additional zone, higher level resource planets will be available.
For more efficient mining, it is vital to unlock zones from the Sector Archive to open higher level resource planets.
Higher level resource planets are available as you move towards the council, which is at the center of the Sector.

Thank you.
