The #SpaceMagic thing was funny, but to actually answer your question, from my interpretation, all focuses and specials are derived from the Traveler. I think Warlocks will be able to actually use more of the Traveler's magic, but the Titan's fist of havok and hunters golden gun are derived (somewhere) from the Traveler. I read this from the game informer January issue featuring Destiny. It's a good read and that was my interpretation of the different magics.
