(Spoilers?)



1. Hornet has a scottish accent, no explanation for this I just think it would fit her
2. Ghost is mute due to the fact he's a vessel, however when he wasn't a vessel I think he did have a voice
3. The Pale King always snuck out of events like dinner or parties to go experiment with void
4. The White Lady wrote the song you hear in the nursery room in the white palace/when you die and go to collect your void

I have more but I won't post them unless u wanna hear them
