House Spirit

Source Monster Core 2 pg. 194
House spirits are shy, often helpful, sometimes wrathful fey who dwell alongside peasants and farmers. They reside in the house, the yard, the granary, the bathhouse—wherever people build and live. Due to this proximity, house spirits often take on the mannerisms or appearance of nearby mortals. Their reclusive nature and tendency to go unseen earned them the moniker of “spirits,” though in truth they're fully embodied fey.

House spirits take an almost parental interest in “their” mortals. Given proper respect, these fey work tirelessly for their charges—they chop wood, care for livestock, mend clothes, sweep the floor, and tend to the stove. If offended, though, the house spirit becomes a menace, frightening animals or children and ruining belongings.

Bound Spirits

Every house spirit chooses a specific place to be their responsibility and their place of power. House spirits can and do leave, temporarily or permanently, but it’s never a trivial decision. Typically, a given location has only one spirit, which gains power if their home is particularly grand. A great palace’s domovoi is fearsome indeed.

Kith and Kin

House fey often treat each other as family. Sometimes, this is literally the case with the domovoi and the kikimora as a married couple, the dvorovoi their younger sibling, and the bannik as a curmudgeonly elder. More often, it's a sort of metaphor among the spirits—though fey treat metaphor very seriously indeed. This isn't limited to just the house spirits, either. A kikimora might call a poludnica a distant cousin or in-law, and the bannik has always had cordial relations with rusalkas and vodyanois.
