i realise this is a very very crude map... but it's something. i hope it serves. two versions, one with the plotted lines and one drawn over thicker.
green dot - port-in
red/orange dot - guardian of blood
blue dot - guardian of mind
pink dot - guardian of heart
light grey dot - guardian of bones
black dot - guardian of elial
dark grey area is where the watcher sleeps
hope these links work...
