As Milton, you have earned the right to sit amongst the Eternals in wait for the end of the mortal world. Yet you are not whole. Your Emination remains in the mortal world, the vegetative state in Albion. And so as to not be alone on the great day of Judgement, you know you must descend to find her. But Ololon, your love, may be difficult to find.

And to find her, you must first 'descend to eternal death'.
