@Himitsudesu That goblin, which you called, "도깨비" (dokkaebi) is his species. An example is a demon. IMP is his role title/job. An example of this is a general demon knight or demon king.
If I was the priest, I would give them a short introduction about the world and set a journey alone somewhere else while saying, "Bye! I hope I never see you guys again in a lifetime. 😊"
Oh my GOSH!! Am I dreaming!! Did this become a manga!!! Thank you author for not discontinuing your novel. I love your novel so much that I recently read your novel again. I know that you won't be able to read this but still, I wanted to put it out there.
@SwanLamp I know it, but I won't say it because that would be a MAJOR spoiler for those who didn't read at least up to chapter 100 in the novel. Also, I bet that the spoiler that you mention would probably be in season 2 or season 3 of the manga.
