Summary:  Napoleon and Illya find themselves on assignment in Transylvania.

Click on the quote to take you to AO3:

There's a dark lantern of the spirit,

Which none see by but those who bear it,

That makes them in the dark see visions

And hag themselves with apparitions,

Find racks for their own minds, and vaunt

Of their own misery and want.

-- Butler from Peacock’s ‘Nightmare Abbey’
