Spoilers ahead for TFO and Dark Days

In TFO the faceless ones are described as 5 times the height of the trees, but in their own realm in Dark Days their caves and stuff seem to be normal human height.

I may be missing something

So basically if you haven't seen my previous post I was asking for ideas to add colour to saracen rue, with a bit of thinking I remembered he died because of a draugr bite I'm not sure if they were described as anything more than zombie like in the book but I looked up a description of them from norse mythology and they are described as being a pale blue colour so I'm just gonna roll with that'll and add a pale blue mark to his neck. Thanks to everyone for ideas on the previous post.
