OK, so, let me clue you in: the elderscrolls dont mean anything
the glyphs in the background are repeated in lines. 1, 2, 3, 4, 5, 6, 7, 8, 1, 5, 7, 6, 2, 7, 1, 3, 2, 4, 8, 1, 2, 3, 4, 5, 6, 7, where the first line of symbols is '1' etc. (the exact order may be off slightly, i did it in a hurry a long time aro). 17 circled symbols probably correspond to daedra, 8 not circled to aedra. together they align to the Thief constellation , a lame (imho) reference to the nature of the quest.
[edit] of course dev laziness can be made to mean something... but i gave up on that.
