Either.
Both.
Ernalda (and some other Earth-Goddesses) lead to being Queen -- it's more often a "soft power" role (negotiating, alliances, trade, compromise, etc); but it IS rulership. It's just not a very traditional mode for Sartarite rulership.
There are exceptions, as always -- the Feathered Horse Queen, afaik, is often a war-leader type figure. Your Glorantha May Vary, My Glorantha May Vary, Chaosium's Glorantha May Vary, Greg's Glorantha May Vary. And they do.
