Daedric lore is something I've always enjoyed exploring in and out of the Elder Scrolls games. Powerful conjurers are able to summon many Daedra, something we, as players, can also do. However, one thing that always intrigued me was the stories of mages who would summon Daedric lords and speak to them in order to learn more about them and the realms of Oblivion. I think it would be an immersive experience for us to be able to converse with the higher-level Daedra that we summon in the game. It would be a great touch for academic-type characters, and a great way to introduce more Daedric lore.
Would love to hear other people's thoughts on this.
