Now that the roadmap is sorted out I'd like to take a break of ugorians and tell you 'bout the youngest mythology on the list - the one that appeared sometime in Renaisance and came shaped and known to us only in 1936th with "The Malachite casket" by P. P. Bazhov. The mythology of Urals came to be a mix of a well forgotten Russian paganism, ortodoxal christianity, and a folklore of a local Mari and Bashkirs.
Mistress of the mount Copper aka Malachite maiden, Stone maiden, Maiden of Azov.
The most known of those characters. A guardian spirit or even a deity of Ural mountains, local mineral deposits, miners and all kinds of local reptiles.
She can take shapes of a beatifull girl with malachite-green eyes and hair of the finest and the thinnest strings of copper/black braids with copper ribbons, a tiny lizard, something in between or an unseen presence.
Mistress is strict but kind, especially to simple hard workers. If she favors someone, she can show that person a copper deposit, share some magical jewerly, or even get him out of troubles. However her favor is much harder to obtain for someone who's in charge of things - Mistress either doesn't like to share her power over the region, or is just a kind of an anarchist. In one of the Tales Mistress turns a bailiff hunting her in a block of malachite.
In another one she tells the protagonist - serf Stepan - to tell his bailiff go get lost from the Krasnogorskiy mine. Stepan did as she asked, and suffered a lot from the bailiffs anger. Then the Mistress appeared and saved him, after wich she gave him a very transperent hint on that she's kinda lonely in those mountains. But Stepan refused, as he wanted to stay loyal to his bride Nastyona. Respecting such loyality and honesty, Mistress gave them both freedomn and a Malachite casket full of jewerly.
Mistress is also said to posess The Stone Flower - an artefact of an unknow power and untold beuty.
Flameleaper. One more local female spirit, a little girl who's dance is said to show the location of a gold deposit. She's a trickster however, and her hints are never true. But she seems to share Mistress'es attitude towards serfs and in one of the tales uses her heatkinesis abilities to save one of them during winter.
Blue hag. A spirit of an unknown nature and purposes. Always wears blue. Can take shape of a hag, a simple girl or a beautifull woman.
