Daybreak announced this week that on September 4th, it is going to merge the population of Stormhold with Antonia Bayle. This means that Antonia Bayle is going to see an influx of refugees while Stormhold will be shut down for good. This will be slightly tricky due to the fact that Stormhold was a time-locked expansion server, but that will come to an end as Antonia Bayle is a normal server ruleset.
There’s a lot of details that Daybreak covers concerning potential name conflicts and the transfer of mail and housing, so read up on the FAQ if this server merge affects you.
