remind me on how data center works

[Ghishlain]

Unfortunately, no. You will only play with other servers on the Aether data center. Excalibur and all other servers on Primal are not accessible.

You may of course, make a new character on Excalibur or transfer an existing character there.

Just to expand on this a little, here's a list of all the data centres and what servers are part of those centres. You can use this to determine what servers you'll be matched with since you're on the Aether data centre.
