These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Genius Bonus: The runes used in Chaos spell effects is deeply evocative of the Furthark script. One is even exactly like the sowilo rune. Another is exactly like Ingwaz. There's also a bit of the Anglo-Saxon script in it also. Makes sense, the guys who serve Chaos are Vikings and their leader's called Thorgar.
