hi there,
i've never been one for thorough background story research *cough* at least not in the hellgate universe. so, with my limited understanding of that, i'd like to know more about the logo summoning circle:

specifically, what's the glyphs in the outer ring, is it a language, what does it say, what do the lines mean, what's the purpose of this summoning circle, are there others like it? tell me anything and everything

thanks in advance
