So sorry, Lopov, that I made you doubt yourself. It has been YEARS since I went to Shivering Isles - I knew it was somewhere in Crucible, judging by the expansive space and the decorations, but honestly, I was surprised, very surprised that I got it right. I was going by the previous responses - museum, etc that I came to the answer through process of elimination.
As for my picture, yes, Kane, it’s the portal to Sovngarde atop Skuldafn. I am constantly surprised (and I suppose I shouldn’t be) by the parallels between identical locations in ESO and Skyrim, or even Oblivion whenever I venture into Cyrodiil or the Gold Coast.
Your
Kane!
