Give Jitters' Completed Journal to Bishop Farthing in Stormwind.
Go to the city of Stormwind and speak with Bishop Farthing in the Cathedral of Light. Give him Jitters' journal and tell him you mean to face Morbent Fel.
Although Stormwind has forsaken Darkshire, Farthing is a kind soul and very wise. He may help you on your quest to save us.
Your mission is perilous, but hurry, [player]. With each passing hour, the shadows of Duskwood grow ever darker.
