the first and second choice is reminiscent of the wife candidates in Gaius Marius' Dynasty quest...
Maria was a fiercely religious Ulric worshipper/werewolf who thought books were dumb and his Ice Princess was frail and whispy.
Johanna is a fun loving adventurer who doesn't really focus on one religion as superior or needed, who can drink with the best of them and my Ice Princess is a cold woman who has ice in her veins and isn't frail by any means.
But I guess I can see the whole 'fighter and Kislev' parts as being similar.
