Quests and audio are now implemented in Arena Rebuilt. These were the next major systems after the population work, and both are now in place.
I have also completed a heavy bug-fixing pass across the project. That work focused on correcting issues and tightening the build before the next milestone.
With those systems implemented and the bug-fixing pass complete, I am now packaging the first playable version of the mod.
Packaging is underway, but this is not a public release announcement. There is no public download or release date yet. I will share another update when the package has completed its remaining validation and is ready for the public.
