Thought about spells

Thanks for the reply. It really helps me understand the form of magic other than the magic that need to be cast.

Just to the idea about creating blizzards by saying "BLIZZARD".
Well, pushing a trigger does not make the gun to fire. It just starts all that mechanics needed for the bullet to leave a barrel. So yes, it is possible to use something as simple like saying a word to trigger a reaction. But You would have to be in tune with the universe at extreme level to create blizzards that way.
And what the magick is and how it works? Nobody can in fact answer that question. The scary fact is that it does some how work, this is all that matters for now.
