So, the Daedric Prince of Destruction and Change, Revolution and so on. Is he chaotic? I think he obviously is, but some apparently disagree, because the definition doesn't say chaotic is causing chaos But being in a chaotic state. Yet if you cause chaos, are you not among that state of chaos? Mehrunes Dagon does that to mortals, and even in his realm, he and his daedra although having a hierarchy still exist for the purpose of causing war, destruction, suffering and strife.
"The Deadlands are a Daedric realm of Oblivion created and ruled over by the Daedric Prince of Destruction, Mehrunes Dagon. The embodiment of its creator's sphere, the dimension is fraught with natural disasters and destructive change. The realm is covered by an ocean of lava, scattered with scorched volcanic islands and ruined structures. Many lesser Daedra roam the realm freely, but Dremora dominate the hierarchy. Very little flora grow in the realm's hostile environment. Burnt grass and dead trees dot the landscape, while Bloodgrass, aggressive Harrada Roots and poisonous Spiddal Plants grow abundantly in the charred soil."
As my awesome Dragon Priest friend Hevnoraak said, it's literally a chaotic place.
And what of the rest of the daedra in general? Like sheogorath? His daedra may have order over the mad citizens of New Sheo, but the land itself is completely chaotic, not to mention they continuously have wars amongst each other to gain his affection.
So are the daedra chaotic in general? Would you agree that it is merely different levels of chaos that they cause? And if not all of them would you say most? They are the embodiment of change and change often leads to chaos.
