How WoW Forever Realmless Works
The September 17 official developer Q&A gives the clearest explanation yet: players choose a ruleset instead of a realm, while regions, data centers, character assignment, and latency still matter.

Choose a ruleset, not a realm
Forever decouples the social experience from selecting a traditional named realm. Players choose rulesets such as Normal, PvP, or Roleplaying. Hardcore is not available at launch and is planned to arrive later as another ruleset choice.
Characters do not freely hop between rulesets
A character cannot hot-swap between PvP, RP, or other rulesets. The developers compared this to current WoW: changing a character’s ruleset would require something like a character transfer rather than an instant toggle.
Dungeons and raids stay inside your ruleset
Factions remain separate: Horde and Alliance cannot group together. Dungeon and raid groups are also limited to players on the same ruleset.
Hardcore is enclosed, but dead characters can transfer out
Hardcore arrives after launch and remains isolated from the other rulesets. When a Hardcore character dies, it can transfer to another game ruleset; the Deep Dive specifically says PvP becomes a transfer destination.
Collections and Legacy cross rulesets, with a Hardcore exception
Collections and the Legacy System are account-wide across normal rulesets. Rewards earned in Hardcore can be available on other rulesets, but progress from outside Hardcore does not flow back into Hardcore.
Battlegrounds are an exception
Most world and social play is organized around your chosen ruleset, but Battleground queues may place you with players from other rulesets.
Realmless does not mean regionless
Regions such as EU and CN still exist, and geography/data centers still affect connections. Realmless removes traditional realm selection; it does not put the whole world into one physical region.
Oceanic players and Australian data centers
Oceanic players will mostly be hosted on Australian data centers while retaining the option to play with US friends. When a group spans distant geographies, the selected data center can change and ping may vary.
US and Oceanic share a ruleset-wide Auction House
The Q&A explicitly says Oceanic and US players share the same ruleset-wide Auction House, an important economic consequence of the Realmless structure.
Realmless also changes character naming
Characters use a first name plus a required surname, with the full name unique across the region rather than a traditional realm. A name used on one ruleset is unavailable on another ruleset in the same region.
Language preference and PvP faction balance
Players can choose a language preference, and the system aims to place them around players with the same preference. PvP rulesets will also use mechanisms similar to Season of Discovery to target Horde/Alliance faction balance.
Global events should still feel like global efforts
For events that should feel server-wide, such as an AQ-style opening event, the team says it is designing the system so the experience still feels like a global effort. Specific AQ implementation details were intentionally not revealed.
