Tree of Savior NA / EU will be launching its free-to-play version after maintenance today. In addition, the brand new SEA server, Varena, will be opening as well. The team will be monitoring incoming players to determine if any new servers will need to be added to the currently existing ones.
Please note that [SEA] Telsiai will temporarily become exclusive to players already on the server, meaning new users in the SEA region will need to start playing on Varena. We won't be restricting access to any other server.
