very crude translation of this finnish childrens song, sorry about that.
In the song, the bogeyman/spook/gobling/Groke starts to make a ring of children, calling first someone, and then they call someone to the ring and they call someone to the ring until all kids are at it. Was (is?) very popular in kindergarden, the caretaker usually being the bogeyman and starting the play by asking some random kid first. With this play you got to know if you were popular in the same way as being the last kid when you are dividing kids to groups in a team sport.
A finn can see that this bogeyman is the Groke from the Moomins, and this brings us to the latin words:
Lux: light
Febris: warmth
Caritas: kindness/love
Gemma Rubra: red jewel (I couldn’t find a translation to “ruby” for some reason?)
In the Moomins, the Groke is always seeking the first three things, and on occasion, the fourth.
I thought it’d be funny to initiate it’s summoning by offering these things to her. (oh yeah The Groke is a girl so)
