No oceans near us. Lakes, yes, but no real oceans unless you go to the Fyreborn Islands. My father and grandfather took me wave whumping often as a kid, much to my mother and grandmother's annoyance.
Yes... Our caste system for males are Blood males, Warlords, Princes and Warlord Princes. For females it's Blood females, witches, Healer, Priestess, Black Widow and Queen. Females can have more than one caste, only two males in the history of the Blood have held more than one caste. One of those castes were always ever female. My great-great grandfather was not a natural Black Widow, but his son, my great-grandfather, was. And the only male in the history of the Blood to *be* a natural Black Widow.
