Tuleloits (also known as The Invocation of Fire) is a song performed, written and produced by Kerli, sung, for the first time, at Pühajärve Jaanituli 2018. A "loits", as Kerli herself said, "is a sacred song in ancient Estonian witchcraft, sung to bring about anything the practitioner wishes, to worship or to thank deities and nature". Throuh Kerli's Instagram story, two member of her family (probably her mother, Piret, and her sister, Eliisa) can be seen providing studio vocals for the song. The song is included in her third studio album Shadow Works.
Through an Instagram post, Kerli said that she had the intention to sing, at Pühajärve Jaanituli 2018, a "loits" to "the fire spirits to harness their power of warming one's soul and cleansing outdated energies". Since she couldn't find any "loits" that fit her desire, she wrote a new one. While describing the writing process, Kerli stated:
While dancing around to a shamanic drumbeat and invoking: "rise up, rise up, little spark" in my Moon Temple, I suddenly noticed thick smoke moving through the trees towards the house. I had lit the woods on fire and it took me many hours covered in soot and many buckets of water to put out the flames.
