((
Would I know the same things about Mel as Beirus does, or would I have to think about it myself, first? If so, I'll do that now.))
Sit back down at the table and examine the partially disassembled machine if Mel leaves.
If she doesn't, ask her what's wrong.
Feel free to ignore the part below if you don't want me doing two things at a time.Ritual circle of some kind, probably from Perplexicon, probably powerful from the large size of it. Nothing about what it does though.
Since I said 1 or 2, and you've answered, I'll have a go, I think.
Hmm. Nonsense words, probably meant to be runic or magical. "Ishtal" shows up twice, further implying that the words have meaning. The runes with "Ishtal" are the ones connecting the other circles together.
The words exist in a circular border around the runes, and not all the of the runes have them; the words possibly refine or focus the power of the runes, another layer of complexity.
The runes and the words are within circles, some of which are connected. Notably, every circle inside another circle is connected, pieces connecting together to form a whole.
There's a circle of runes within the larger circle of runes; the runes inside the inner circle are isolated from the runes in the outer circle, except by the connecting line, a "spell" within the "spell".
The connecting lines are either straight, curved, or zigzag; the zigzag connection occurs only once, while the curved connection occurs between the central rune of each "spell" (the one with "Ishtal"), and runes with an odd word. The word has no space to give it a beginning or an end, so I can't tell what the first letter is; it's probably not an anagram, so I'll identify it with the first letter at the 12:00 position, spelling "Chotar". The curved line might be indicative of the "Chotar" word, or more likely it indicates what kind of effect the rune it connects has on the overall "spell". The zigzag line only occurs once, in the inner "spell"; I'm thinking it either mean "input" or "output".
The central runes are larger and more complicated than the other runes, probably the "core" of their "spell".
The "core" runes are both the same size. As are the "Chotar" runes, and the runes without words.
The outer "spell" is less complicated (fewer runes) than the inner "spell".
There is one "Chotar" rune in each "spell", and both have the curved connecting line and are larger than the unworded runes, but smaller than the core runes. A power source, maybe, or an opposite for the zigzag connection; one might be the input(s), the other the output(s).
All that adds up to... not much. Without knowing what the words or the runes mean, I can't decipher what it does. I'm fairly certain about the role of the core runes, and the "Chotar" runes are probably one of the three possibilities I suggested. The zigzag-connected rune is an oddity; it has a special connection, but no word around it, and is the same size as the other unworded runes.
I'm gonna take a shot in the dark here and guess that this adds up to a summoning or undead-creating ritual, with the inner spell summoning or creating the actual creature, person, etc. being summoned or created and the outer spell binding it to the service of the caster. Because why not.
