Hello and welcome! Delmoth is correct. Currently we're in beta and testing. The main focus is trying out content and looking for bugs. Unfortunately the consistency and linearity of the content is disrupted due to the way it is setup for testing.
We appreciate your feedback in that the content is hard to find, for when the server launches we intend to implement a system that beter advertizes where to get content and what to do!
Checking in a few months later -- we have added several shops and npc dialogue across the city. Things will hopefully feel less empty.
If you're able, I suggest you ask on the discord to try and find some others to test with. Our beta population is relatively small so we try to co-ordinate dungeon testing batches with those that we have available.
