When you are in the right location to read Benosch Ironsprocket's Enchanted Field Guide to Luclin, you will see a message in your chat window "You have entered an area that could prove fruitful if examining the spelled book." The areas listed below do NOT have to be followed in order.
Otherwise, run it in this order and take the tamed Shik'Nar from the Tor to the Spire at the end. You can also fast travel back to Grieg's Spire and do the travel in opposite order.

Read the book to complete the quest. To get the next quest click on the option to read the faint text.
Note: Once you complete this step in the TS line, you can purchase travel baubles in Sanctus Seru. They are Will of the Blinding, Will of the Coast, Will of Seru and Will of the Wracklands. Purchase from bartender at ( 11, 181, 176 ) Copy/waypoint 11, 181, 176. These make travel throughout Luclin much more efficient.
