This is a simple retexture of the Telvanni gate at the Gateway Inn at Sadrith Mora that aims to be more realistic.
There's also a version where the Telvanni symbol shines with light. Because light doesn't work well with parallax, there are two versions: one without light and with parallax, the other one with light and no parallax. Each package comprises both versions. (more images)
