The Aether that's driving the Krall mad is strange, and it's affecting the Krall physically. Krall who've gone mad are reported to be...well, green, if the report's correct.

They're abnormally strong and completely insane. You should be able to handle them, though.

Player: "How am I supposed to collect Aether?"

If you hunt Insane Dark Shamans or Insane Cursers in the Contested Expanse or the Kunpapa Outpost, you'll be able to get the Strange Green Aether. Of course, I'm not certain it's green--I haven't seen it. It's definitely dangerous, though.

Go to Heiron through the rift, kill Insane Dark Shamans and Insane Cursers and bring that strange Aether back here. Any questions?

Player: Accept.

Remember, the rift appears in Mahisha's Nest, southwest of Kidorun's Campsite. When you get to Heiron, take the road south from the Decayed Grove past the Black Tears Swamp, and that will take you to Kishar Village.

You'll need to go past the village and up the hill to the east. That's where you'll find the Krall who've gone mad. Keep in mind, Insane Dark Shamans and Insane Cursers are known to be extremely violent, so please be careful.

Player: "I will. Blood for blood."

Player, I see you've returned. What do you have to report?

Player: "This is the Aether you asked for."

You haven't been yet? Did Sorgrim not tell you the way to get there? We need this now, Daeva, not tomorrow. Get moving.

Player: "The task is mine."

This is the dangerous Aether, is it? Hmm....

I appreciate your efforts in this matter, Player. Here, take this. You've earned a reward for your actions today.
