Well, I made this long ago for myself because I hate Lydia and love certain famous supermodel 😉
So, I edit the housecarl of Witherun with something prettier.
Yes, this mod is a replacer, not a standalone.
Barbara has better stats than Lydia, she’s a dual handed warrior, but I edited her for people who wants to play with just one hand and two handed with the respective perks.
She will level with you up to 100, she´s marriable, can be steward, or just your favorite follower. Her voice is “FemaleYoungEager”.
