Laws of Silvar Dynamics
The mention of Hakaril has a tendency to summon him to the location of the conversation. The governing theory behind this is that Hakaril can somehow sense that he has taken a relevant place in the conversation. Given this, receiving attention in other locations provides an irresistible lure that draws him closer.
Once Hakaril appears in obedience to the above trends, he will then inevitably dominate all action and conversation until such point as he is no longer present. Even then, he occasionally takes the action with him to a new location, continuing to be the focus of all things relevant for no discernible reason.
