A wonderful Ref sheet of my Wyvern called Shadow.  raxrie was the lovely artist to put this fine creature together
However be careful when around this wyvern as he has a ravenous hunger but dont worry he doesn't bite..

Shadow originally started out as a black dragon but ended up becoming a Wyvern but who knows with how this fandom works he might be able to change into one or the other, and unlike Winter his maw doesn't glow but it does have a rather sickly yellow looking saliva color to go with the dark depths but however inside the belly does have a bit of a bioluminescent slime.
Shadow might not be one of the flashy types of wyverns or dragons around but why would he be when he attacks from the darkness. After all my name isn't for show
