What is the canonical habitat range of glaives and how does there habitat affect them if at all.

Originally, glaives were a forest dwelling species, but are generally successful in any area with lots of natural cover. Since conditions on Adveneden are deteriorating, they've had to spread out much more to survive!

Are there any past ice ages with receding glacial ranges that would result in migratory behavior amongst glaive wyverns, and if so does this result in a sort of seasonal wanderlust?

Adveneden is currently undergoing an ice age and extinction event! As a result, they've had to expand outside of their traditional habitats for better environments and food!

While glaive packs are traditionally territorial, conditions have made it so they have to range much further. Individual/transient glaives tend to wander a lot more!

What all is the world like? Is it a more arid, or more frigid, or temperament or mediterranean etc climate? Is the gravity any different then what we're used to here on earth? (for example to help with flying or such)
Any notable landmarks or features in the setting? (like how we have the Grand Canyon or the Great Barrier Reef here)

The world is a mars sized planet rich in heavy elements, giving it a close approximation to Earth gravity. Landmasses tend to form along the equator.

Like any world with shifting tectonics and erosion, a wide variety of spectacular formations have formed across the world. I'll be detailing a few in the near future. :)

Sounds interesting, looking forward to seeing more!

what are the governing laws of your universe, for example, is magic a thing and if so how does it work what are it limits

Physical laws are very similar to ours, though with a touch of soft sci-fi thrown in with alchemical biology some species on Adveneden exhibit!

What of volcanism? (Volcanoes)
Nearest ones, big ones, etc. Any located in unusual places, etc.
Remember that high elevation (mountains) are typically low on volcanism (as they are caused by different, and diametrically opposed parts of tectonic activity).

The planet features a particularly large and near moon. Similar in size to our own, but twice as close. Tidal forces from the moon drive violent tides, weather and volcanic activity. A decent portion of equatoral mountain ranges formed from volcanic activity, rather than tectonic activity early in the planets life cycle!

who are the major players in your worlds great houses/kingdoms are the human anthro both?

Three species have reached a stone age level of development before the ice age event started to reduce biodiversity. All of which are big, monsterous species smart enough to adapt to the changing environmental conditions of the planet. There are no political entities larger than local tribal affiliations so far, though one of the species have regressed into barbarism from an early civilization.

Humans and other anthros are not canonically present on Adveneden, but that doesn't mean they can't visit this savage world. ;)

What are the other two native species? Are they ones that've shown up in your gallery before?

I've yet to introduce them!

are there canonical glaive sub species that have come about due to environmental pressure and natural selection

There haven't been isolated groups of glaives long enough to really develop regional differences. A lot of life on Adveneden is very 'set' within their species though with recent conditions, that is bound to change as glaives spread out farther from each other looking for new territory and food.

you have mentioned the worlds moon are there other heavenly body's and are they know, even just as tribal gods, by the species of Adveneden?

The old civilization was just starting to chart the stars and the 'wanderers' when they collapsed and their glyphs lay in ruins. Though it seems there are far less than the Sol system.

What kind of heirarchy to their tribes have? Do they fight over resources, or solve their matters through less violent means?

The packs are generally a form of cooperative anarchy for survival, with experience carrying more weight. Most glaives would rather move on that risk serious injury over food unless they really had to. Squabbling can be common, though it seldom comes to outright violence except in the most heated circumstances.

how well do glaives interact with the other species that are on a similar level of development as they are?

All other sentients are roughly on par with stone age development, and mistrust can happen just as easily as cooperation where resources and food are scarce!

One species has the beginnings of a bronze age civilization that regressed due to the climatic shift.

I'm just going to absorb all this information now so I can somehow correlate it into my Glaive, Storm's background.

Do Glaives know about Masquerlisks and do they like them?

X3

While not canon to Adveneden, Glaives LOVE Masquerlisks and would adopt a wingload of them at a time! :D

Have you fully dumped the lanterneer idea? Or are you gonna keep some of that tribalism?

I'm reworking the idea!

Have you given thought to the future of Adveneden? What's in store for glaives if they finally form a cohesive civilization, or will it take outside influence to get them out of the stone age?

It will take a LONG time to happen, but it can happen. :)

Canonically, are Glaives a Feral, or an Anthro species, or both?

In Adveneden, they're feral but much farther down the timeline they're anthro!

oooooohh!

total shift, or a portion of the demographic- like, is there a sizeable portion of the timeline where both subspecies co-existed?

I imagine there's isolated glaive relatives in the future where the anthro ones live. :)
