10th war has been started. The quest dialog and turn-ins, up to talking to Sentry Badain in Great Divide, are working. The event itself has a bunch of lua code, but no way to activate it yet (that I know of). Sentry Badain doesn't have a quest file that runs the event yet.
https://github.com/ProjectEQ/projecteqquests is the active quest repo, with weekly updates. If you browse the git, you'll find the ring event. Just not sure how complete it is yet.
Good luck!
