Not all. I appreciate all omakes.
If the omake is not canon compliant for some reason, I'll threadmark it under Apocrypha. Canon ones go to Sidestorys. Anything written from a modern-day perspective will most likely go to Apocrypha, simply because it would be impossible to not contradict something at some point in story updates.
As for the Siberia hunch, the world looks significantly different than the real one, so there is no direct parallel that can be drawn. For the name I would suggest "Seashell Culture" as that is a common material and motif in Sea People art and thus their material record.
I gotcha, and seeing as there's no direct comparison to be made, I'm just going to plop them down in northeastern Siberia, a little west of the south edge of the Alaska land bridge. (Don't remember what it's called.)
Tv Tropes
Mythology and Religion - Unbuilt Tropes
-The Seashell people of coastal Siberia have a lot of this in their folklore.
—Merwedor, their sea goddess who gave them the gift of boats, is one of the earliest examples of a
Science Hero, straight out of the mid-20th century. Yet not only is she a woman, but the problems she faces are not transient, one-off threats, but persistent, adaptable forces in their own right, and Merwedor struggles to keep up. She always manages to avoid a
Pyrrhic Victory, but the death toll can be quite high before she manages to implement a solution - a far cry from the "Science Solves Everything" attitude of the 1950s-60s. Some experts believe that her struggles are an allegory for the desperate fight for survival against the harsh Siberian winters.
—Skerhogis is a dragon - one of the earliest known examples in folklore, in fact - and yet in his earliest appearances, he's a giant eel.
Adaptation Species Change? Well, yes and no - Skerhogis created his physical body out of bits and pieces of animal corpses, so it's pretty clear he just upgraded to a better body. Furthermore, despite being a dragon, he breathes ice, not fire.
—-Speaking of Skerhogis, he's a pretty tough customer - so tough, in fact, that he single-handedly justifies the
Villains Act, Heroes React trope. This is clearly demonstrated when Merwedor gathers up her allies, Segbherg and the Sky Child, for an assault on Skerhogis's frozen fortress at the edge of the underworld, and are soundly beaten despite triple-teaming him. The heroes react, because against a threat like Skerhogis, it's all they can do.
