I was just been curious to why he wanted to know, not saying he shouldn't know but as I said you wont find much about it, the only thing I know is from word of mouth down generations, whither it's fact or not I can't say, But what I've been told is that the trinka five is the Romanian way of describing the five elements of earth,air,fire and water, maybe moon or sun aswell can't say for certain which five it is...., which Romanians believe each element contains a spirit for that said element. But as I said just word of mouth and no way to prove it as fact.
I think the trinka part is actually derived from the the word tricksta and associated to the lore of crows. the latter is just my view on it.
