This is where I will be developing the HW counterpart to Mogreth in broad strokes. This is necessary for a re-vamp of the Selhomarr HWR, which was first written before Mogreth (and a pile of other setting details) even existed. That being said, the following is guiding my thinking (taken from a discussion on Mystara Reborn):
Mogreth in the Hollow World
by Geoff GanderAs things stand in my head right now, Ka would have scooped up a couple of villages, or maybe a town, in Mogreth prior to the flood that wiped it out. Being an ascended reptile, Ka has sympathies towards all lizardfolk and given that he did have (covert) worshippers in that land he would want Mogreth's unique culture to be salvaged as much as possible. He probably had to argue for it forcefully in Pandius (despite being Mr. Hollow World himself) before the other Hierarchs gave him a green light to do it. So he grabbed a community of lizard men and troglodyte faithful and deposited them in the Hollow World. Naturally, a few devotees of Other Beings managed to sneak in as well, because there's nothing Yurrgh-Thal and his ilk like more than a good cosmic joke, and, well, the Burrowers hadn't done their jobs properly thus far.
However, the other Hierarchs wanted the Mogrethians set down in a place remote enough that, should their darker tendencies reassert themselves, they wouldn't mess up other cultures. However, leaving them *too* isolated might allow them to become a dominating force in the Hollow World...
...Just like the Selhomarrians were threatening to become, after ~5000 years on Suridal.
OTHER THOUGHTS
I want to avoid scope creep on this project. I know there are a few cultures neighbouring Lhomarr (e.g., Nevumm, Orimul, Suur) that were wiped out, which logically could have been transported to the HW. Also logically, the Immortals might have placed them near Selhomarr to preserve a kind of normalcy... or they could really have decided to shake things up and place them far away, but this would mean figuring out the impact on other cultures that might already exist in said locations.
The point is, while speculating about what those cultures are like for development purposes would be an interesting and fun exercise, it's a rabbit hole I want to avoid because reworking Selhomarr is going to be a monumental task on its own. For the time being, I am focusing on Mogreth - which was notionally located in the large swamp in north-central Suridal - and even then my intent is to develop it enough to make it a workable setting in its own right, so that it can support my work on Selhomarr. I have other projects I am working on that I want to keep on track, and I am wary of taking on too much. While I lack the energy and amount of free time I had in my 20s, I think the extra 20-odd years of writing and game development I've done since I first released Selhomarr should produce something people will like.
The other thing to consider is if Mogreth was destroyed c. 2000 BC, this means about 3000 years in the HW to work out. A lot of things can - and certainly did - happen.
