We Have Darkvision
Empyrean- Monster Friends
Empyreans might look a little bland but that's probably just because they are.
However, there's some very cool aspects to them and we can easily imagine a dozen different ways to implement them into your campaign in interesting ways. The raw descriptions in the Monster Manual leave a lot to be desired, but they have so much more potential than is presented.
So come give the episode a listen, and let us know what you think. Are Empyreans as bland as we think they are? How would you make them more interesting? Are they Friends? Are they Fiends?
