Note: This makes the mobs in The Grey non-hostile.
Meet the tegi at ( 532, 87, 425 ) Copy/waypoint 531.93, 86.97, 424.87
Wait for the Ritualistic Intent ceremony to start. Do not move off the platform, wait for the Tegi Sympathizer Flyer to appear on the post after the completion of the ritual. You MUST have the Ceremonial Amulet of the Tegi equiped BEFORE stepping on the platform, or the event will not trigger. Equip it, move away and on the platform again.
At some point the High Shaman will say, "Fer da Gahds!" and leap into the shadowy magic and disappear.
Note: This is a timed quest.
Note: It may take a bit of time, but should be at least once every Earth hour, more likely ~15 minutes.
Note: Do NOT talk to the NPCs. It doesn't speed things up. It may slow it down.
Note: The Tegi Sympathizer Flyer appears on post behind you. Don't jump into the crater.
Note: Make sure you wear the Ceremonial Amulet of the Tegi or you wont get credit.
