Adrian cannot really do anything to the gods that visit Avalon because he was cornered by them once in the meeting. It seems that all of them are stressed and want a change in environment which is why one or two gods can descend to Avalon a day. Even the gods have gotten the concept of a holiday because of a chatty champion from one of them.
If one were to describe it then they had unionized against Adrian for always making them work. In the end, he had to agree to give them a vacation in Avalon one or two at a time. Some really hide themselves like mortals but some could not bother at all and just hide their divine auras.
Adrian did tell them that they should at least pretend to be normal humans but the other gods do not even bother. They feel restricted in the skin of another which is why Adrian no longer cared as long as they do not create trouble. The problem is that the guards and the elders are the ones having a heart attack each time the god encounter mortals.
