System and dominion limits

Part of the Star systems guide

Your System Limit is how many systems you can hold. Your Dominion Limit is how many dominions you can hold.

The systems and dominions counters in the bottom bar
The Systems counter shows how many systems you hold, and its bar fills as you near your limit.

Your System Limit starts at 1 and your Dominion Limit at 0. Active lexes raise them. The tables below list which lexes raise each limit. The Expansion Charter game modifier also adds 1 to your System Limit and 2 to your Dominion Limit. It is not in the tables below.

The System Limit breakdown shown when hovering the Systems counter in the bottom bar
Hover the Systems or Dominions counter to see your limit and where it comes from.

What they block

At your System Limit, these are refused:

At your Dominion Limit, these are refused:

Colonization and Control check the limit again when they finish. If you are at the limit by then, the action is cancelled.

A conquest that succeeds while you are at your limit can still kill population and damage buildings, but you do not take the system.

A change of active lexes that would leave you over a limit is refused. Your Navarch, Erased and Siderian Limits work the same way. See Agent limits.
