Great Ustyug
Realm of Ded Moroz
Location: Para-Elemental Ice / Fog of Unyielding Frost
This Winter wonderland is shielded from adversaries by the dense fog of the region. Great Ustyug is a surreal and whimsical burg where all buildings are made of ice. Though unlike the ice of, say, the Tsardom of Silver, these ice blocks are colourful. Some say, they are made out of frozen fruit juice—although you’d have to be real barmy to try and lick something at this temperature. The palace of Grandfather Frost is pretty tame as far as divine palaces go. However, it always welcomes travellers—which is very good news, because despite being made of ice the place is always magically kept warm and cozy.

Margarita notes: While this homebrew power is based on Slavic folklore and beliefs, the amount of actual information we have on pre-Christian Slavic deities is so minuscule that building any kind of lore out of it is impossible. However, there are a lot of folk beliefs about things these deities are thought to represent, which I have worked into the piece.
