Meet Shrieker, the kenku wereraven!
This is a character my friend runs in my Curse of Strahd campaign, he is a kenku blood hunter/paladin mix who has evolved throughout the story thus far. This poor bird is touched by the demon prince and his vile black blood causes him to transform into a monstrous were-raven, sometimes causing him to lose control. With the help of his friends and his goddess the Raven Queen he is learning to control himself, lest he lose control and release the beast within.
