Speaking from a purely Larian point of view, I miss DOS2's Narrator.

" Malady " however, was always more of a GM-NPC thrown into the mix. She's the perfect Narrator. Her personality from the previous game screamed for a darker game. Glad she got the gig.
Also has enough playful quality to her voice for the awkward scenes.

Overbearing god voice would just be too much, I can see her at the end of the table explaining things. Which is the point.
