The Nature of Magic

I hope this thread will generate some interesting ideas and debate about magic in Thedas based off we have learned thus far. I am drawing on all sources; games, source books, novels and the on-line Core Rule Book for lore about magic.

First off, since we are likely headed to Tevinter next game and so should be encountering blood magic once again, I am currently a bit puzzled over where blood magic derives its mana. According to Last Flight it definitely doesn't come from the Fade and it is evident to any mage using the normal source of mana that the blood mage is drawing their power from somewhere else. According to the CRB magic permeates all living beings in Thedas, whether animals, plants or sentient beings. It also states that some believe that magic is the power that gives life. This would seem to clear up the question of where blood magic derives its power. Whilst some humanoids such as mages and elves have greater concentrations of magic in their blood, it would seem that everyone is endowed with a little.   However, this leads to a new problem.   If blood magic does not derive its power from the Fade, then theoretically a Tranquil should still be able to utilise blood magic and still do spells, since the Rite cuts them off from the Fade.   So is it just that they haven't had the incentive to do so (having no emotions to drive them) or do you actually need emotions to do magic?

When Solas is discussing with Cassandra how a Templars ability to supress magic works, it entirely revolves around their ability to reinforce reality so "the Fade has nowhere to gain a foothold and the magic disperses".   Surely though that only applies to mages who draw their power from the Fade.   If a blood mage does not draw their power from the Fade, then according to this speech the Templar should have no affect on a blood mage, yet we know they do.   So how do you suppose this works?

When talking with Vivienne Solas confirms that there is another source of magical power, Blight magic.    The false calling was Blight magic; the demon merely amplified its effect over a wider area.    Solas also comments that the wine glass with blight magic in it is poisoned.   Essentially there is nothing good about Blight magic and anyone using it will eventually be consumed.   In the Last Flight it is again made clear that the Archdemon's Blight magic is being drawn from somewhere other than the Fade.  It is not drawing it from the same source as blood magic, since Solas has no problem with blood magic being used, so clearly not "poisoned".   It would seem the only other place it could be drawing its power from is the Void.   This would make sense since essentially the Blight is an anti-life, destructive force and so likely to derive from the antithesis of life that is the Void.   It is the complete opposite of the Creative force of the Maker (or whatever you like to call the originator of the world).    The thing is, if it doesn't derive its power from the Fade and it doesn't derive it from the life force of created beings, where does the power come from?   Is there in fact another entity in their universe that is the polar opposite of the Maker?    Why does a place like the Void that is essentially an absence of anything, a negative so to speak, give any power at all?   Still I assume this is what Corypheus meant in his memories when he says they didn't make the darkness, they merely discovered it and made it their own.    This would suggest that the Void, or at least a portal to it, is what lies in the Black City at the heart of the Fade.    Any thoughts on this.
