Baba Yaga is an incredibly powerful hag who lives in a hut that walks around on massive chicken feet. Strix lived with her for a time and learned how to bake. When Strix used the scroll given to her by Shemeshka to summon the Sewn Sisters, she noticed that the writing looked just like Baba Yaga's. 
D&D Lore[edit | edit source]
Baba Yaga has a number of popular adventures to her name. The initial Baba Yaga's Hut ran in Dragon Magazine. In 2nd Edition, there was a new version of the hut released in the form of a 48 page module written by Lisa Smedman. In 4th edition, Craig Campbell created a fully-fleshed out hut that revises and completes the 1st edition adventure.
