I could be wrong, but I vaguely recall the Shivering Isles being Sheogorath's Plane of Oblivion - which he seemed to share with Jyggalag - who would emerge every 1000 years or so to reassert himself. This is very much a theme corresponding to repressed emotional issues which, likewise, surface periodically to reassert themselves until acknowledged and accepted for what they are. This theme is combined with the "Mania" versus "Dementia" theme which seems to mirror the impact of bipolar disorder on artistic expression. Superficially, the words "Mania", "Dementia" and "Fringe" have their own denotations or connotations in the context of psychology - so, never mind the dog, beware of the pun!

Running with the most obvious theme, being psychological, Jyggalag and Sheogorath appear to be alternating aspects of the same Daedric Prince. However, while Sheogorath's state of mental health is openly acknowledged, Jyggalag seems to be very much in denial concerning what, thematically, appears to be a frighteningly bad case of obsessive-compulsive disorder - which emerges with his compulsion to render everything in his domain in uniformly mute forms and colours - namely grey; however many shades there may be.

So, in answer to the original question, it could be argued that Jyggalag is present, at the time of the Last Dragonborn in the Fourth Era, deep in the psyche of Sheogorath who is deep in the psyche of Pelagius the Mad. I noticed that someone mentioned the idea that the Hero of Kvatch mantled the Daedric Prince of the Shivering Isles. It seems that he is even in character with the nature of someone who, as former Champion of Cyrodiil and former Hero of Kvatch, has a tendency to champion various causes - even that of Pelagius the Mad's sanity.

Superficially, the key outcome of the contest is one of order or madness (chaos) which seems to be a ripe old Easter egg hearkening back to an old alignment system once used by D&D + AD&D - but probably long forgotten by those of us holidaying in Tamriel. However, if we extrapolate what took place in the Shivering Isles (around the time of the Oblivion Crisis) as the nature of a regular event, it would seem that a regular mantling of Sheogorath would impart sudden personality changes every 1000 years which, in turn, introduces an all new aspect of madness to the mix.
