MMO Culture is reporting that the publisher, OMG Digital Entertainment, is bowing out and will close the doors on the game in Taiwan, Hong Kong, and Macau on November 18th. While the game could keep on going with another publisher, so far Bluehole has been unable to find a substitute.
OMG said that after the shutdown it will hold on to TERA player data in case a new publisher is found. This means that it might not be farewell forever for player characters.
