Now that it has been several months since Harbinger came out and also just now The City, for Digital, it may be time to muse about the next expansion(s) that are possible:
There most likely will be some new Realm, that bridges The Woodland and the Highland. I'm ready for that, but also hope that this realm is as different from Deep realm as Deep is different from Nether; meaning something out of the box, perhaps. The possible adjacency to The Graveyard makes me want some aspect of that to be involved (a Pet Semetary? An Ancient Cemetary).
Someone mentioned a Rivers expansion, which seems like a good idea, and to me, also opens up an expansion to it; "INVADERS", which maybe could have several different scenarios, like Harbinger. An invasion from Pirates or renegades, and invasion from sea/amphibian type huminoids, or lizard men. Anything that could develop a mechanic of these invasions coming through the Sorn river.
I myself, previously mentioned Giants expansion, perhaps a play off of Dragons, but instead of Draconic Lords, maybe 3 or 4 different types of Giant races; Storm Giants, Ice Giants, and so on.
I still would like to see a NPC with a female badass, like an Uber powerful Witch or Queen of Vampires.
What about something that is the opposite of the Blood Moon? Something that can use the Day/Night mechanic but is more oriented towards .... Sunlight? So instead of Lunar events, Solar events? Of course having a big bad might be harder to conceive, but there are possibilities... going back to Lizard huminoids maybe?
