What does that mean? It means that this merge will see a move towards "truly international worlds" for the game where multiple languages will be seamlessly supported on the same shard. A brief FAQ also addresses dupe character and guild names, with Trion offering free name changes for those moved characters and guilds.
The merges begin during the normal scheduled downtime for North America on Wednesday, October 23 and for Europe on Thursday, October 24.
