Damn spiffy. Themes do change things, 'tho.
Jotuns -- technically giants, not titans. Titans are more of a Greco-Roman concept, aren't they?
Man -- the Tuatha make me think more of Ireland than England. "British", perhaps, or the Isles of the Mighty.
Marignon -- more French.
If you're going to note assassins (e.g. Machaka), they also are available to Abysia, C'tis, Marignon, Pythium, R'lyeh.
Pythium -- under 'special', I'd suggest easy Communion.
Pangaea -- add Blood, for Pandemoniacs.
