Rumblings From Beneath

Background
This quest appears on the Merchants' Guild Board in the city of Amaranthine. It appears that this quest only becomes available when you have unlocked the entrance to the Smuggler's Cove at the back of the Crown and Lion Inn, but this needs to be confirmed.

Walkthrough
Once you have received the quest from the Merchants' board, go to the Crown and Lion Inn and enter the passageway to the Smuggler's Cove.

You will be confronted by a group of Darkspawn - four Genlocks and a Genlock Emissary. Dispatch these and the quest will be updated.

Return to Kendrick to claim your reward.

Result
The Darkspawn bodies will drop random basic loot. Despite the promise in the quest description, it appears that Kendrick gives you nothing more than his thanks.
