There is no single mythic origin story recorded for alkas; rather, they are attested in the historical record as a longstanding category of sacred site. The first written mention appears in Adam of Bremen (1075 AD), and Christian sources of the 15th–16th centuries continue to describe them, showing a trajectory of persistent cultic relevance in pre-conversion and early post-conversion periods.
Alkas are natural places rather than built temples: groves of trees (often described in sources as pine woods in historical accounts), hills, fields, lakes, rivers, wetlands, bogs, and islets occur as alkas. In modern survivals these natural sacral spots are sometimes accompanied by syncretic Catholic markers such as wooden chapels, crosses, or idols, but the defining feature in sources is a preserved natural locus of ritual activity.
Alkas are not described as personified beings with autonomous powers in the cited sources. Their culturally ascribed functions are ritual and symbolic: sites for burning sacrifices and making offerings, locales associated with burial and the dead, and—according to oral folklore—gateways to other worlds where souls of the dead might dwell in trees. They are treated as set-apart, holy ground whose sacral status is maintained by prohibitions and priestly acts of consecration.

- conditionbreach of customary taboos (prohibitions can be overridden by outsider action)
Wards

- conditionguarding and exclusion (community prohibition e.g., Christians excluded from grove entrances to avoid 'uncleaning')

Baba Yaga
Baba Yaga is an ambivalent female figure of East Slavic folktale tradition, depicted variously as a fearsome, child-eating crone or as a helpful, maternal donor. She is associated with the deep forest, a hut described as standing on chicken legs, and the motific accoutrements of a mortar and pestle.

Bhoot (bhoota)
A bhoot (also bhoota, bhoot, bhut) is the culturally specific term across parts of the Indian subcontinent for a perturbed, restless spirit generally understood to be the ghost of a deceased person. Sources describe bhoots as arising when a person's death or post-death circumstances prevent them from moving on — for example violent death, unresolved affairs, or failures in funerary rites — and the term appears frequently in modern South Asian media and discussions.
