How to reach Castle Mistmoore
Reaching Castle Mistmoore is childs play! From Plane of Knowledge take the Felwithe portal to be take to Greater Faydark - where you see me at in the picture above. Once you're here head a bit southwest to the Lesser Faydark zone line.
Zone to Lfay then skedaddle on across the zone far to the southwest until you reach Castle Mistmoore - shown in the picture below.
