Your characters and crown purchases are not shared between the PC/EU servers.
If you earn CP200 in PC-NA server, it does not carry over to PC-EU server.
ANY purchase you make at the Crown Store including DLCs can ONLY be used on the server you purchased it on.
So if you purchase the Orisium DLC pack on PC-EU server, it will NOT cross over to PC-NA server.
Furthermore, the crowns deduction will apply accountwide – i.e. the new crowns balance will be reflected on both NA/EU servers but the purchase will only be tied to the server you bought it on
Exceptions Apply
ANY purchase/changes you make to your ESO account outside of the game will apply on both servers.
Examples
- Buying a special edition of ESO that comes with additional DLCs or upgrades unlocked
- Applying a code such as a torchbug pet
- ESO Plus
- Winning a Twitch crate via drops
