Hello!

I think, after searching endlessly, this is currently something that is completely missing from the Fabric ecosystem. This could help enhance the Taterzens experience dramatically. I think some features could be in order to start a quest you'd have to talk to a specific NPC, and then be able to do different things such as turning in items, talking to other NPCs, etc.

A lot of people have suggested that already, although I won't be doing it myself, at least for now. Sorry.
