On August 15, 2022, Zenith will be removing a good chunk of their shards.
This could be a good thing when it comes to finding people to play with. Less shards means that more players would be on the same shard rather than players spread across several different shards.
Characters are not locked to a specific shard, so you could easily move to another if your favorite shard is being removed.
You can find a list of the shards on the official post.
