"Thousand-year-old wind" I believe is supposed to be Kazagiri Chitose. (reading the hiragana on the second link in the OP) So there is at least one name. The others are player's choice.

All that other stuff for the details... kind of an eye strain, so I know it's going to take me a while to figure it out.
