The way that Era servers are laid out can be a bit confusing. If you’re looking for an Era realm to play on, I hope you find the following helpful!

Format
This format will be used to describe each realm/cluster.
| Field | Explanation |
|---|---|
Region |
US East/West or Oceanic |
Type |
PvE or PvP |
ClusterName |
If a clustered realm, the “main” realm for that cluster. This is a community colloquialism, not an official title. |
Population |
A visual indicator of the cluster population. See below for details |
Realm1..N |
The realms that are available in the cluster. |
All Realm1..N servers are clustered together and act as though they are a single realm. You can choose any realm in the set, it doesn’t matter which.
For population, I’ve attempted to give a visual indication for population. This is a rough estimate based on the information found from the above noted sources.
(Alliance) :: 
(Horde)
- - Several guilds logging raids, more than any other server.
-
- Several guilds logging raids. - - A very small number of guilds logging raids. One or two at most.
- - No raids have been logged.
Raids logged in the last 45 days or so will count as activity but please note this could be anything from ZG to Naxx. For more information, please create a character on the realm in question and engage the player base directly.
Finally, I will do my best to order these roughly by population and then by realm/cluster name. It will not always be perfect.
Active Realm Clusters
These realms/clusters are currently showing as having recent raids logged. If you’re looking for an existing raiding community, you can likely find one here. Community size fluctuates, see sources listed above above for up to date information.

Note that this doesn’t include the non-clustered realms. See the Active and Inactive sections above for a comprehensive listing.
If anybody has any questions or would like to request updates/corrections, please feel free to let me know.
. Maybe also throw it a bump now and again. It seems there’s some confusion as to what the Era realms are, how many there are, and what the clusters mean.
