Note: Meet Thirin Veliumdelver at -9.69, -64.84, 222.46 to begin his next quest. This is inside the underwater cave.
Note: If you need another totem while continuing the quests in this area, there is an interactable rock up at Cragged Spine where you first found Thirin. You can only see if you don't already possess a totem. Click on that rock ( 292,47,175 ) to receive another totem.

I was able to discover that the Ry'gorr orcs are tunneling a network of tunnels underneath Erollis. No doubt they plan to attack from right under their feet.
