Some time ago I was pondering about the look for Sadrith Mora. I was thinking what kind of rock formation would make most sense and compliment the mushrooms, but I came to a weird conclusion.

Why not have the whole island overgrown with tangled roots, and have bridges going over them and through? This idea was stuck in my head, so when Grumpy asked me to do a concept of a Telvanni tower I jumped into it.This design of Tel Naga is a mix of Tel Mithryn from Dragonborn and original Kirkbride's concepts. I didn't use much from its original looks, but I don't think that symmetry worked very well for Telvanni anyway.
