This state of affairs might change soon, as the game is being transferred to another publisher. WarpPortal is taking over the game, and in an effort to make it an easy transition for players, all account information is being transferred to the new publisher. Dragonica, the EU version of the game, is unaffected.
If you missed out on this transfer, the new publisher has a Q&A on the forums, and a date for relaunch should come soon. We'll keep an eye out for Dragonica Online's reintroduction!
