This is a Guide Quest. On Live servers it can only be received from a Guide. On Test there are no guides so NPCs exist there to give out the quests. Any information regarding starting zone and mob are from Test.
This quest is given out by Volunteer Guides during Nights of the Dead. On Test servers it is given by Falcra Nightwanderer on the Nektulos Forest docks.
In Antonica, all of these creatures can be found just outside of Blackburrow at -1466, -3, 857 and beyond the waterfall to the east of Blackburrow at -1814, -14, 826 . Starting at the waterfall and going west is the fastest way to complete this quest.
I've met a number of odd characters in my day, but they usually don't ask me to go around cataloging the other oddities I could encounter. After reading this little book, I'm not sure I want to take on this task. Then again, what harm can come of cataloging a few creepy-crawlies?
I need to locate and catalog a number of creepy creatures in Antonica or Commonlands.
