YGMV - Your Glorantha May Vary. We repeat those same four words so often that it's almost some sort of religious mantra. But how do we actually practice what we preach? What are some ways, big or small, that y'all's various Gloranthas have varied? How much stake do you place in published sources, and how much do you make up or homebrew yourself? I'm hoping that this thread could be a place where people can get ideas from each other for fun or interesting ways they could vary their Glorantha, in large ways or in little ways.
Here's a few of my own to start it off:
1. "Humanized" elder races. I'm not a huge fan of totally alien nonhumans, though a fair bit of weirdness is alright, and so I like to make everything a little more relatable and playable. And yes, this does extend to dragonewts 
2. Nicer Dara Happa. IMG, Dara Happa is still an extremely hierarchical society with a tendency towards pomp and arrogance in the upper echelons, but even without the Lunars it's not the total repressive misogynistic place that it sometimes looks like in canon. By extension, Yelm is a bit of a nicer god too.
3. Illuminates are sociopaths. The way I've interpreted it, Illumination is basically believing (and having your belief reinforced by the universe) that there's no moral difference between, say, raping and murdering a homeless man or buying him clothes and a hot meal. Therefore, Illuminated people seem emotionless and react purely based on their own logic or out of necessity. They can act emotional if they need to, but this may require a roll. One way to spot an Illuminate, especially an inexperienced one, is to watch their reaction to what should be a shocking or traumatic incident: if their reaction seems delayed or insincere, they could be illuminated.
4. Dragonewts and dreams. My interpretation of Draconic philosophy is that the world is made of dreams. The Cosmic Dragon is Ouroboros within its own dream, and everything else is dreams of the Cosmic Dragon. Dragon magic is basically lucid dreaming, dragonewts are the dreams of the eggs, and the goal of dragonewts is to "wake up" as dragons, then engage in another series of evolutions until they wake up as the Cosmic Dragon, and then the same until Ouroboros reawakens.
