Ive a good idea of the identity of the Blood Wolf.
When I first saw him I was like…
“aight 33% chance I’m right”
Inarius should have REALLY been the final boss and he should have killed Lilith… but she somehow had more plot armor than him… Such is the curse of modern writing.
As you progress through the campaign, you will know who the Blood Wolf is. Wont be a secret for long. 
Yeah, she is really lame TBH. Should have been Inarius or one of the prime evils.
