Klara’s reference is the Romuva

Romuva is a polytheistic pagan faith that asserts the sanctity of nature and ancestor worship. Practicing the Romuva faith is seen by many adherents as a form of cultural pride, along with celebrating traditional forms of art, retelling Baltic folklore, practicing traditional holidays (Baltic aukuras), playing traditional Baltic music, singing traditional dainos (songs) as well as ecological activism and stewarding sacred places. Practitioners of Romuva claim to continue Baltic pagan traditions which survived in folklore and customs.

Whatever religion the original inhabitants of the Baltic region had predates recorded history. Mesolithic hunters, gatherers and anglers of the region practiced a religion focused on their occupations. After this, Indo-Europeans entered the area and brought with them their Proto-Indo-European religion. This religion, including elements from the religious past of the region, evolved into paganism which is attested in the Middle Ages and later.

The Baltic aukuras or "fire altar" is a stone altar in which a fire is ritually lit. Participants wash their hands and face before approaching the aukuras, and then they sing dainos or ritual hymns as the fire is lit. Food, drink, grasses and flowers are offered to the flame as the group sings the dainas. After the primary offering, participants offer their own verbal or silent prayers which are carried to the Gods with the smoke and sparks of the flame.

Romuva primarily exists in Lithuania but there are also congregations of adherents in Australia, Canada, Russia, the United States, and England. There are believers of Baltic pagan faiths in other nations, including Dievturība in Latvia. According to the 2001 census, there were approximately 1,200 people in Lithuania identifying with Romuva. That number jumped to around 5,100 in the 2011 census.
