Ah yes, so easy on the eyes. Thrynn and Brynjolf sporting new looks.
Thrynn is from WolfGrimDark and it does require MFVM. He’s quite powerful and his dragon shout causes a lot of fights with other followers if you have multiple followers. At least Ulfric shouts his enemies apart, Thrynn does this to his friends.
Brynjolf with new hair is from Males of Skyrim by Aberin. This mod is listed as Adult-only content but it only replaces the appearance of males. Since the author is not native to the English language it could be a misunderstanding of how to list and tag it. It does not content nude content, extreme violence or otherwise mature content. HearthFires is required.
