My wife and I were just mentioning the other day how we can have video chats with family half way around the world, for free. When we were kids making a long distance call to someone a few counties away was a big deal and we didn’t talk long because it would cost too much. Wild stuff.
My setting has a lot of nautical aspects to it, including lots of drowned and sea creatures. One of my players in a captain of a ship (they’re all level 15+ now, so he’s worked his way up there). I’d have the blind character have a parrot that narrates the world to them, much like a DM.
