So if understand correctly, the church of diagon may be related to the deep one, who was responsible for Juno’s death. I’m thinking we should look into them to figure out if we need to take revenge.
Correct. This is why Solomon looked into them previously.

That would seem to be the next logical step, though Bear was waiting on a response from Kara, or for that matter any other input on how to deal with the threat posed by the priest.
Sorry, I did not realize you were waiting for me. Though I have control of many NPC/characters, I am trying to let the players drive everything. However, will post for Kara now.
