Laoni Reista says 'You do seem a bit young. We shall have to test your mettle. Within this temple, you shall learn to swim as fast as the swordfish and attack with the bravery and skill of the shark. Are you willing to [assist with the cleansing of the ocean]?

Laoni Reista says 'Go to the waters near the harbor. We have heard of Qeynos' rogue guild attempting to smuggle our valuable Vasty Deep water from Odus by way of swimmers. We require proof of their involvement. It is said they often carry special coins. Return one of these coins to me.
Go to the harbor as she says and go diving. I found a named NPC called Taler Bilge swimming around the harbor. She swims very fast. When killed, she drops a nicked coin . Give this coin to Laoni Reista for this response:
Laoni Reista says 'Good work. You have shown these rogues who are the better swimmers. Now we have proof of their involvement. You are a fine addition to the temple. Take this small reward. Go, and serve Prexus.
Your faction standing with DeepwaterKnights got better
Your faction standing with HighCouncilofErudin got better
Your faction standing with Heretics got worse
You gain experience!!
You receive 4 copper from Laoni Reista.
The reward that I received was very poor - something like a torch.
