Jyggalag, Daedric Prince of Order, has broken free from his demented other half for a day.
No he hasn't.
Why don't you take him along on your travels?
Because I'll go along too.
You can find him wandering around Helgen near a Chest of Light.
They're always attracted to shiny things, aren't they?
Yes, precious.
Always.

Not a Sheogorath clone.
Perhaps a copy, without an original.
A simulacrum, if you will.
Even if you don't.

----------

Kill him.
Don't kill him.
Marry him.
Don't marry him.
Get the key.
Open the chest.
Summon the horse.
Where's the vendor?
Buy the rest.
