I am trying to research this but it's confusing. Have several questions not finding answers.
1) What exactly does a housecarl do?
2) Do you have to have one? Should you have one?
3) I found rats in my cellar would a housecarl keep them or outside mobs away?
4) What if I don't like my housecarl's dialog? Can I unemploy them?
5) Can I get a different one after choosing one?
6) I have Hearthfire expansion and built a house near Falkreath with permission from Jarl Siddgeir. Do I have to become his thane and then am I stuck getting http://www.uesp.net/wiki/Skyrim:Rayya as housecarl?
7) Does it matter if I get a housecarl before or after husband and kids (also pert to Hearthfire)?
Thx for answers in advance.
