Dear Al-Du-In,
We here in Sovngarde have taken a petition, and it is unanimously agreed: We would very much like you to stop eating our souls. Honestly, we're the good people, that's why we're here and not in Oblivion getting eaten by Dremora.
Now, we would like to make note, we're not complaining or trying to tell you off. In fact, quite the opposite. It is also unanimously agreed throughout Sovngarde that we should provide you with a suitable alternative. To that effect, I should write to inform you that directly adjacent to this wonderful realm of ours lie the hunting grounds of the Daedric Lord Hircine. To be certain, you, Alduin, immortal world-eater, are far more powerful than he, and we believe that his soul and those under his charge would be a far preferable choice for you to consume. The evil souls of Daedric champions are, after all, quite powerful and would prove most nourishing for you. And besides, we're good, they're evil. Better them than us.
Thank you, son of Akatosh, for your kind consideration.
Sincerely,
Ysgramor
