Glagoljica ic christian letter , she is asking bout pre-christian=pagan letter. Anyhow to answer your question , we had runes … i am 90% sure and we can find them in various locations in slavic lands , simmiliar to nordic but not the same. I studied that with Svatoslava alrdy so I am pretty much lazy right now to write bout it again … wait till she gets here I am sure she ll post u some pictures etc. Unfortunatly our "runes" are not decrypted (if thats the word , hope u know what I mean)
