For the reference of my plan, copied from my post on page 1810, which is basically lost to the depths of time at this point lol.
The Runes I had in mind for this were to use the Banner Master Rune of Grungni, the Rune of Lighting, and the Rune of Fury. The purpose of these runes is to create a combo that channels the furious power and damaging energy of a thunderstorm and to tap into the storm imagery seen in some of Snorri's visions.
We need to start with a general storm concept. The only runes we have that have something to do with wind are Grungni's runes, the Master Rune of Currents (and that only tangentially), and the Master Rune of Blizzards, and the only general storm runes we have are Grungni's runes which is notable on Stormwrath. The Master Rune thus forms the basis for the combo. We don't have any upgrade materials for it, but that's fine since its a Master Rune and already very powerful in its own right, and in the case of the other two runes their ingredients are meant to add conceptual notes and raise them up to fit with the ambition of this project.
For the Rune of Lightning I've chosen to use Kholek's Brain for a couple of reasons. Kholek was a lightning using, magic using entity who directed his powers with his thoughts and will, and his mind witnessed the dark pact of immortality between the Dragon Ogres and the Chaos Gods. Because of this pact they sleep through the ages until lightning fills their brains and bodies and awakens them, filling them with furious energy and vigor.
Because he is a lightning using entity I don't think its going to break the rune, because the elements in question align and regular runes normally have reagents below our level of abstraction and aren't as finicky as Master Runes. I'm hoping that since Dragon Ogre's brains and minds are empowered by lightning they draw in, if we use it in this rune like this it might give us the ability to be empowered by lightning as well which would let Snorri draw power from the Throng-Storm of Kraka Drakk. Or perhaps something to simply direct and coordinate the absurd amount of power going into this, since the Banner-Cloak is being forged with Barak Azamar and Zharrgal as tools.
As for the Rune of Fury I want to use the Sky King's Feather. The reason for this actually circles around to the Master Rune of Grimnir which I'd bet my left shoe has the Rune of Fury as one of its components and the Master Rune of Grimnir takes tier 2 Griffon Feathers as its ingredient. With the Sky King being such a powerful griffon that should improve the Rune of Fury, and because he is also a magical griffon who rules over storm and thunder I hope to use his Feather to tie the Rune of Fury to his furious storm themes.
The idea is for using the ingredients is Coordination and Power, all tying together to create a Primordial World Set with Barak Azamar and Zharrgal.
