((I’ve received help with this from Labyrinth. LOVE YOU! She offered the bird. ‘Cause I have no knowledge of birds. Or many things, honestly. Should probably work on that.))
It’s often you see Grim Reaper drawings featuring the Reaper and then a black bird companion, usually a Raven or Crow. Oddly enough, Caelem has neither crow nor raven, but a collection of birds by the name goshawk.
As seen above, they are black and white birds with red eyes. While a rather common type of bird, they can be rather fearsome to look at, and a large gathering of them tends to signal that he was arriving… If the storm that gathers beforehand doesn’t do that already.
