Well, Ein is traveling to the dwarven kingdom to go meet with the king, I assumed it was at this point that my character would find out the primary plot point/prophecy about us defeating the evil dude. I assume that via the magic of the dwarven kingdoms underground tunnels that I can pop out just about anywhere and meet up with anyone. So, Ojo's character wants to meet more humans? I would say you two head to where darkwolf is at, meet up there, and I will stumble across you there as well and we can go on our marry ways towards defeating the boss.
That sounds reasonable enough, that by following the "wrong" path through the dwarven tunnels you find an exit to the surface world.
