Tyrna is also available as a follower! Tyrna - Nord Follower on Nexus - Steam Workshop

HOW TO USE THIS PRESET

1. Open the console by pressing º
2. Type "setrace nord". Your character will now become a Nord, this will not mess up with your attributes or skills.
3. Type "showracemenu" select Nord race, Default Setting. You'll find her in the preset located at the first position of the slider.

I recommend to start a new game, changing your character's face in a current game can cause weird glitches (dirty face).

If you want her to look like the screenshots, you can use these mods:

ApachiiSkyHair by Apachii
AOF Believable Hair by AnOldFriend
Coverwomen - Look 3 by mrLenski
Natural Eyes by nevenbridge
