Taking the Thunder Pass

Steps

 * 1) gather 6 lorpa vines (sparkly non trackable plants on cliff shelves above village)
 * 2) kill monitors for 8 toxins.
 * 3) Speak with Dorl in tent next to Guld. He gives you 3 pieces of spear wall to place in the Pass. ( -1276, 25, 1457; -1425, 49, 1364; -1408, 93, 1100)
 * 4) Continue north on that path in search of Greymast. You find a stunned Corith Midner on ground with 2 Allu'thoa Landhunter standing over him. Kill them and speak to Corith to finish this quest. He also updates Dark Threats on Dshinn to: help Corrith get to safety.
