That's basically the canonical answer... the future is a post-apocalypse after Argrath and his ilk ruin the world.

This is what I found when reading up on Talastar. They used to have a (kingdom) king of Talastar, but since a couple of decades, the post is open (it had a Lunar puppet in the end anyway). Instead we have a king of the Bilini, which is such an enormous tribe (25 clans or so, making the Colymar look small!) that the king of the Bilini comes pretty close to the king of Talastar. It's pretty much a theoretical distinction that he's a tribal king instead of a kingdom king.

Shouldn't Gloranthan monarchs have a cube of authority rather than an orb?

All the oddball weirdo munchkin “heroic” characters (oh, so many, even in canon!) that don’t seem to fit the setting or behave like Gloranthans are in fact dimension-travelers from our world who try (poorly) to pretend that they’re natives.

Or as the Lunars call it, "Illumination".

You will not get a complete picture, no matter what you do. The Sourcebook is a travel guide; the Guide is an encyclopedia. Read the Sourcebook first, the Guide second. Don't try to read too much of the Guide at one time, or your brain will try to escape your skull.

On the other hand, while "Orlanth Chaos-Friend" is certainly out there, it's not inherently impossible (cf. Hellwood Krjalki Yelmalio on Soltaks's page). Sedenya illuminates him into understanding that Chaos, too, can be compromised with...

Every non-broken dwarf agrees. Don't be a person!

Orlanthi manage this without Illumination!

We're getting a pretty skewed view of the opinions of Chaos in Glorantha by seeing it mainly through two of the most anti-chaos cultures out there, Orlanthi and Praxians. In the world at large, Chaos is often baked in with other unacceptable stuff, like the rebelliousness mentioned here, or as part of a "Krjalki" classification in the West, where what matters isn't whether you're Chaos, but whether you're a monster.

Mortals preexist the gods and exist independently of them, and all of the gods and the entire Gods World is retrocreated through subjective belief and worship. There is nothing about a god that isn't in a myth, as they have no separate existence. (Prove me wrong, though!)

One of the HW books note the interest a Sakkarite Lunar occupation unit has in the cult of Yinkin.

Correct. RQG is unusual for an RPG in that thrown weapons are really good, both because they don't have movement restrictions like this (RQG skirmishers had better use thrown weapons!) and because you get half DB.

Related issue: to what extent do people in Glorantha know that they are "low on Rune Points" and "need a refresh"? They obviously don't count the points (Paulis Longvale notwithstanding), but they are presumably aware that worship is necessary to replenish rune magic. Can they tell when the tank is getting low? In this case, they should do minor worship whenever they need to fill up.

Can you airlift a duck, or does that count as "flying" as well?

It's likely proportional, but it probably shouldn't (if we want to dig down into that kind of granularity) be affected by whether you had an unusually good year, for instance. And I'm not at all sure it's renegotiated yearly - historically, these kinds of things tended to be very stable. (For instance, some classes were impoverished because they had fixed monetary values for rents, and then they were subjected to inflation and couldn't increase the payments, and this kind of thing took decades to occur.)

I would love to see examples about level of attendance, size of sacrifices, time expenditures and so on various sizes of holy days have on a clan level. How many cows get sacrificed on the typical seasonal holy day, compared to a minor holy day?

The x percent can probably be regarded as a simplification for gameplay - in practice, I don't think a farm (for instance) is supposed to tally its total production and send off 20%, rounded to the nearest value in Lunars. It's far more likely that your stead is obligated to provide the temple with n bushels of rye and two swine, or something along those lines.

All ducks are Pain Ducks.

Darkness involves hunger in Glorantha. If you eat a lot, you get big.

Also, articulated gauntlets would seem to be remarkably high-tech for Glorantha.

Anyone using glasses knows how cold that can get, but I imagine that’s about the skin contact. Wearing metal greaves on bare skin in the cold is surely awful, but that means that you don’t do that.

I'm sure that state of mind is widely shared with youths in Orlanthi society!

Famously:

This is the kind of thing where every religion will have its own answer. To the Orlanthi, for instance, the soul is the Breath (a very common theory on Earth as well). When you're born, you draw your first breath (I don't think they need a theory of souls beyond this). When you die, your breath leaves your body. I would imagine a lot of Orlanthi mysticism is about stuff like the Breath of the Cosmos and so on.
