Here are my new renders of new Elder dragon champion and world boss - Drakkar!
As you can see, he has very detailed model and its the same size type as Vlast, Glint and Elder Aurene.
I made comparisons with a human, Aurene, Vlast and Claw of Jormag (they are both Jormag's champions so it should make sense).
I added those pictures on wiki and also a measurement of his size, in Trivia on Drakkar's wiki page.
Enjoy this beautiful creature!
and one render from perspective:
more are coming - renders of Elder Aurene and Kralkatorrik!
