In general when it come to deathlords, yozis etc...sure they are all powerful but whatever happens, they can't escape one truth. We are exalted, sure at low essence we don't even compare to them but exalted are literally the ultimate weapons against anything. I mean  the exalted fought the primordials! Keeping exalted in check can only work for so long until they rebel and take over, no boss is safe.
