TLoS - Niadhogr and Syrreth

I think most of these refs will be in pairs or group depending on relevance (like, each group of guardians will have their own pic), other lone characters will be individual... 

Anyway, Niadhogr and Syrreth. I'm not going to say anything about their roles, but I'll leave some facts:
- Niadhogr is NOT a 'Light Dragon'. He actually has no more affinity to light than any other normal dragon.
- Neither of them are mortal or alive... anymore.
- As such, they no longer retain their original, natural appearance - at least not in physical form. Same with their names.  
- They are neither gods nor immortal. 
- While Niadhogr is the size of a large dragon, Syrreth's size and proportions are not natural. 

Edit: Congrats to those ten people that made it before I changed the description and removed what I quickly found to be major spoilers xD Don't tell anyone...
