What could be the next DLC of the game?

This week I have enjoyed the DLC of the Crimson Courts; the flagellant has flagelled the monotony I had developed after leaving the game half a year, although the districts have caused me some headache: they require an overly expensive investment that will then give a limited or partial benefit.

On the other hand, I've really marveled at the courtyards with the idea of insectoid vampires who, I believe, are invulnerable to the sun and scatter their disease like zombies.

All this has given me what to think about the future of the game. What could be the next great DLC of the game? What do you think?
