Blood magic according to the wiki:
In the contemporary world, blood magic is described as being one of the more "sinister" types of magic. Blood magic is the magical practice of using blood, life itself, as a potent fuel for magical spells. This life may be supplied by the mage, or by willing or unwilling sacrifices. It lets the mage control the minds of others as well as use their very own life force to fuel their power. This practice is so rare in Thedas now that it can now only be learned from contacting a demon, with the risk of becoming an abomination.
Of course it's a wiki, so I am never sure how valid it is.
Invalidated by in game Lore. Jowan never did deals with demons (he certainly would have been abomination bait had he tried) but he was a bloodmage. (Presumably he learned it from the books in the Fereldan Circle Library).
More explicitly, if you are a Warden Bloodmage, you can give Anders the Bloodmagic specialization, and then
in the game Anders comments on you teaching it to him (when he says that the Templars would call him a bloodmage anyway eventually and kill him true or not, and you say, 'but you are a malificar', and he says, "
now I am and don't think the irony has escaped me").
Thus we have at least one case in game canon where bloodmagic is taught sans demon.
In terms of Hawke, if you pick the bloodmagic specialization, Merrill probably taught you.
