Kill nearby Scaleborn droags to search for evidence. Eventually one will drop a small chest which contains a Strangely Written Note, which updates the quest.
Return to Raakil.
Go to the top level of The Temple Grounds and click the big rock tablet at ( -51, 116, -279 ) Copy/waypoint -51, 116, -279.
Find the following pieces of evidence to help you decipher the tablet:
second piece ( -118, 62, -97 ) Copy/waypoint -118, 62, -97 (Note: it is on the right side of the temple on the first platform, tucked up against the wall.)
Return to the big rock tablet on the Temple Grounds at ( -51, 117, -279 ) Copy/waypoint -51, 117, -279. Using the three notes you acquired in the previous step, you must decipher the message from a Strangely Written Note and select the correct answer on the tablet. Selecting the wrong answer prevents you from attempting again for about two minutes real-time.
All you really have to do is decipher the first letter, since the four options on the tablet all begin with a different letter.
The correct answer is For Our Rites.
Click on 6 wind komodo eggs in the area around the tablet. The eggs are ground spawns, bright blue and easy to see.
Return the eggs to their nests on the Vicious Breeding Grounds. The first time you click on a nest three linked Scaleborn ambushers will spawn. You must defeat them and then click on the nest again to get the quest update.
