I have come to the conclusion that the spawning of A ShikNar Hatchling is just one of several “statements†that occur in the zone, to my experience in the channels running here and there and round about.
Other statements: “The ceaseless glare of the sun makes you shield your eyes.â€; “The sky seems unusually dark to the north.â€; “The clatter of loose gravel attracts your attention. Is something up there?â€; “The area is much warmer than you would expect.â€
The one I want is “A ShikNar Egg Pod cracks open, releasing hungry hatchlings!â€.
