Docks

Stone statue heads line the area in front of the docks. If you read the plaque by the obelisk, it provides another riddle: Bow before the Eldest God, whose spark in you doth burn. Breathe his mighty breath into his lesser kin in turn. Do so in true order, and a great reward you'll earn. Circle around to the plaque's opposite side and stand on the pressure plate in the recess. The nearby statue head's mouth bursts into flame, which E'lara can use to ignite her arrow.

You now have to light five statue heads in the courtyard. They must be lit in the correct order. If you do so, the statue head will stay lit; otherwise, it will burn out after a short amount of time. Begin with the one to the right of the Watery Depth entrance.

Follow the first statue's fiery glow to the second statue head high up on the opposite ledge.

The third statue head lies to the right of the magic portal.

The fourth statue head is to the magic portal's left.

The final statue head lies back down the path to the left of the Watery Depth entrance.

Use the fifth statue's guiding light to find a secret passage in the opposite wall. Have Caddoc push the wall section aside to reveal a hidden treasure cache. Loot the rewards inside, including a gold treasure chest and a Crystal Chest, and don't forget to speak with the Deathstone corpse in the back corner.
