Ok, so I travelled with Kim and Callisto to the southrealm after Arantheal took throne, and I went to the north with Kim, we met our agent, Nicci, and killed those guards, even that Kim was sad about that. Then, after the battle, I told Kim to come with me, but now I don't know what to do. There's no quests in my journal about this at all, except that I have completed "Journey into the madness" or something. I lost Callisto somewhere, and now I have no idea where to go.
E: I copied this topic here, gonna remove the original.
