PF1e: Reign of Winter

It has been a century since the immortal witch Baba Yaga last visited the world, and the hour draws nigh for her return. But when she fails to appear in the frozen realm of Irrisen to usher in its newest ruler, pockets of winter begin to grow throughout the Inner Sea. After 1,400 years of perpetual winter, the icy curse of Irrisen is spreading! What links do these strange blizzards and swaths of wintry landscapes have with Irrisen, and is there any truth to the growing rumors that the Witch Queen Elvanna has taken full control of the realm? Can her plans for the Inner Sea be thwarted, or will the Reign of Winter engulf the world?

Freshly starting winter and eastern-europe/slavic themed legendary AP, that has generally good combat/RP balance (the results are varied by the group).

From me you can expect official paizo materials for the campaign with additional maps (dynamically lit) and handouts, some voice acting, API scripts and macro, help with your characters and bookkeeping.
I've been playing and GMing PF1e from the very start (can't guarantee that I know all the rules and classes but familiar with a lot) and try to keeps things mostly RAW, with no 3rd party, variant rules may be used after discussion with players (EitR and background skills are pretty good ones in my opinion). Also, as most official APs, this one doesn't work well with evil characters, so yours are expected to be neutral or good.
