Dirus is the left one and Exomurk is the right.
Dirus is a full on character, whilst Exomurk is just a name and skin. He has no personality, he's not a character and I have no plans to make him one.

However, I will be keeping the name and be using the name for a Pied Crow character I'm making right now.
But he's not just a normal Pied Crow, I have started creating a species off the real life bird. About souls and shadows, I am even creating him a sister. No name yet for her.

Also, Exomurk means External fog.
