Have you noticed ? There are no books in the Erudin Library...

'I can sense the dark magic that rests within this candlestick. I will need you to concoct a divinatory aid for me before I can discern more. Take this suspension and brew it in a brew barrel with one white hellebore, a pouch of the red dust created by the Fire Peak goblin wizards, and the caustic substance used by the Dark Offerers in Mayong Mistmoore's wicked castle.'
