Shezarr is the Imperial version of the elve's Lorkhan, Shor to the Nords.

Of the Divine he is by far the weakest, partly because he doesn't have very many shrines (none as far as I know) and also because Auri-El/Akatosh ripped out his heart and "killed him". That might be why he made Sovngarde, so he could have the greatest human heros protecting him in his weaken state.
