Hmm. This is obviously a devotional bas-relief commemorating the Divine Zenithar, and in remarkably good condition as well! It must have been protected from the elements soon after its creation.
Definitely Zenithar - you can tell by the anvil. Rumors say that one similar to this hung in a merchant hall in a large city, but was removed surreptitiously by a rival guild in the dead of night, hidden, and never recovered.
Yes. Zenithar, the Divine of Industry and Commerce. A worthy Divine. This is a fine piece, probably carved from the living stone by devoted Resolutes, probably in High Rock. It may have hung in the armory of a Fighters Guild once.
Used arcane lights for further study. Storm in stone speaks to minerals where it died. Does not sing of deep ocean. Trees, flowers, petals. A massive fish in a shallow sea.
Tamriel of today has nothing like it, but I’ve read stories from ancient kingdoms where the seas ranged far and wide and teemed with noisome life. Another reminder of Apocrypha.
Clues adding up. Natural life, touched by the tentacles of a Daedric Prince? How much of Tamriel’s past was shaped by natural process. And how much was influenced by the whims of Oblivion?
