The Ephemeral Commission that Khallyon has received is not a coincidence, it is a reminder that The Imperishable Entities are always watching, waiting anxiously for a good show, tempting the Mortals with prizes, making them nervous so the outcome becomes more entertaining and less predictable.
{It must be difficult to look and not do anything on their own… , Even though they are Imperishable, it doesn't mean that they don't suffer the loss of those Mortals they become fond of}
The goosebump that Khallyon was expecting to feel across his spine does not occur, which means that he was right, The Imperishable also suffer.
