Graven Ashe has approved of Caedis' and Radix's plan to destroy the land of the Stone Sea in order to sabotage Nerat's ability to farm and produce food for his troops.
Radix is awaiting your return at Howling Rock. Report back to him and begin the next steps in the plan.
Caedis and Radix tell you about a missing group of Earthshakers. Travel to Gulfglow Oldwalls and find out what happened to them. Talk to Lycon and Basilon.
The group of Earthshakers are in a standoff with a band of Beastmen from the Stonestalker tribe. Assist the Earthshakers and kill or negotiate with the Beastmen at Gulfglow and inside the Gulfglow Spire. Red-Fang is your point of contact.
Approach the entrance to the Spire. You can get through the beasts by snarling at them. Enter and talk to Red-Fang. As you are working with the Disfavored, she needs to be put down. Slaughter all the beasts at Gulfglow, inside and outside.
