Hmm, that is very strange, see some symbols that resemble greek some that resemble runes and at least three that resemble japanese calligriphical
symbolos.
Looks like nordic runes to me, I could be wrong as it has been sometime since I have read anything on it, but I have seen that particular set before
and nordic was the first thing that popped into my head. Alot of folks attribute those runes to wiccan, but don't believe the hype, wiccan is a broad
generalization.
edit: then again it could be tolkien
