Adrian left his two soulbounds for their enjoyment as they should be able to freely wander off inside the territory without much problem. The elves and demons in the territory knew of them which is why they did not bother them. The players that have been given access to Adrian's territory is another story altogether.
Adrian followed the escort in order to see if what this interesting person needs from him. He knows that it is actually the demon elders that they want to see but they are not in the territory which makes the next like in charge be Adrian. He just had to entertain them and get them to stay away if their business is not welcomed.
As Adrian is walking, he suddenly felt a slight headache. The marking that Cain gave him suddenly reacted which meant that a soul fragment of his brother, Abel, is nearby or it just reacted due to something unforeseen. He just received the marking so there could just be side effects from having it.
