Yeah, it's my turn to post in the collab. I've been trying to pull myself together and figure out just how many things I'll have to take into account in that post for a while now, but I'll get it done soon enough... I think. And good thing the RPGuild is back. You did give out your email once before, actually, Nessa (back on page one of the thread, at the time of which I wrote it down on my little note here kept in the most obvious place on my desk, moreso than where I have my hundred or so of other little notes), but I appreciate the thought nonetheless. My own email, in the event of a disaster, is larskennethpetersen@yahoo.com

I did actually start dipping into my old physics documents and start researching a little online to put together a scientific explanation as to where the photons come from, and had thought about several things to point out about photons and their interactions with the mass-bound world beyond that of visible light - things that you probably already know - but luckily I managed to stop myself before I delved too deeply into the mire of science and had to write an entire essay on the subject. Instead I'll give a much quicker and simpler answer: they are formed from magical energy, taken from the Spirit Realm.
And no, the light of the runesword (hmm... English grammar taken into consideration, it actually does make more sense to write that without the hyphen) would not harm vampires beyond simply blinding them the same as it would any other mortal creature. It is not even possible to reproduce the harmful effect of sunlight through magic (not yet, at least) because the reason it hurts vampires is not connected to ultraviolet light, or any part of the spectrum; rather, the light hurts them simply because it is from the sun. Why? Because Rilon decided that it should be that way. He thought it would be fun.
