Regarding Rhun that's what I've been working on. I've unfortunately been contracted by a pet food company in Anyang aiming to expand overseas as a corporate consultant which has eaten up most of my time but there's definitely more content in progress. Rhun itself is honestly just such a big city it's been extremely slow to flesh out. And Drake's Run should lead into the Drakeblood Chapel. It's a pleasure to see you're enjoying the game though! I'll leave a couple images of the in development areas below if you're curious about Rhun and the existing content past Drake's Run.
If you have any questions or issues just make a thread and I'll reply as soon as I see it! Cheers! If you have any suggestions we also do put suggested items in the game sometimes so long as we won't get taken down or sued.
