Ok, but remember, you asked.
So for the most part I really really like your theory! I love drawing scientific parallels between our world and the D.A. world, so I will always add to your theories if I can! One of my majors is biochemistry and we work a lot with nuclear magnetic resonance, so I can only add to your electromagnetic theory based on my knowledge of how it applies to chemistry, not physics.
<snip snip>
I can only add chemistry knowledge to your theories because I know diddly-squat about dwarven lore. And I don't reaallyy think any of my assumptions will be necessarily correct (in-game wise) but it's fun to theorize.
And I'm never on the same time-zone as you theory crafters! Curse being in the middle of an ocean.
I did ask. @w@ Good lord. Thanks for that! Different effect than what I was first getting at, but crazy interesting in a whole new way. "Charged" lyrium being fundamentally unstable and reactive is... hmm. I mean, raw lyrium has to be fatal to mages in a meta-game sense, since otherwise it kicks off a "who has the biggest lyrium pile" war between mages and templars where the winner takes all every time. But there does seem to be a more satisfying explanation here in the idea of lyrium holding an unstable charge- its effect on beings with an open "fade conduit" like static shock but on a nuclear scale. Zapped to death on contact.
...or I may be totally misunderstanding what you just said, given my super flimsy grasp on the subject. *sweats nervously*
edit: groans as she realizes that this theory would make Dwarves literally "grounded". GAIDER.
edit edit: Also kind of weird that it kills mages outright, rather than turning them into something bizarre, given that lyrium's "charge" is (conceptually) the particle version of the Song's wave. I'm more than willing to shrug and walk away from that bit, though.
