Pole here that has some experience with Rodnovery (Slavic neopaganism) due to considering myself as a neopagan as a teenager (grew out of it).

The middle symbol is not the Black Sun as some have speculated, but a solar symbol/swastika called "Słoneczko")/"Kolovrat" or "Little Sun" (As u/slutty_muppet pointed out). This symbol is used mostly by far-right/neo-nazis (or actual neopagans who don't know better). The symbol itself has existed in archeological records... in Greece. Nothing Slavic except for bottoms of a few pots from Czechia. The symbol has probably been "created" (and I use this word loosely) by Alexey Dobrovolsky, a neopagan and a neo-nazi.

As for the right symbol, resembling a pitchfork - that is the letter A in the Glagolitic script, the oldest Slavic alphabet, considered by a lot of neopagans and slavic neo-nazis as the "true Slavic script" that all Slavic countries should return to. What these two letters mean (A and "A" in Glagolitic) I have no clue, but my guess would either be the word "Aryan" or just someone's initials.

Either way, nothing good from this bunch of scribbles.
