After a few more minutes of such rants, he seems to, if not calm down exactly, at least lose the energy to stay so angry. He waddles back to his throne, slumps down, and quietly demands someone bring him gnome heart.

When one poor unfortunate adviser reminds him that he ate the last gnome heart yesterday, he is ordered executed and dragged off. Plates of small humanoid hearts you shouldn't think too much about where they came from are quickly produced.

As he eats, he seems to genuinely calm down at last.

Then you enter all dramatically and he looks up at you, continues to eat, and doesn't say a word to you. Apparently, he wants you to speak first.
