The PVP arena was the first actually functional place to PVP on the server, before more locations popped up. It was built by Cookies500 and ClassyBulb. The current progress is half finished and functional, with plans to add a "End" section and a "Void" section in the near future. What is currently implemented is the "Nether" and "Overworld" sections. Both feature plenty of hidden secrets and parkour, and each have a cave to exit the arena from. While the Overworld section is recommended for beginners, the Nether section and most of the other ones will be much more difficult and deadly to roam across.
The PVP Arena is located in Sovenheim, at the coords of X:996, and Z:-1322.
