The Fisher wants to relive his glory days and has asked you to collect 10 epic fish for him. He believes that the water in Cinder's Cradle might be more likely to carry these extremely rare species.

You can collect any type of epic fish, but it must be at least 10 of the same kind.

A good fishing location is marked on your map, but you can go anywhere you like.

Return to the Fisher with at least 10 epic fish of the same kind in your inventory.

The Fisher is pleased with the epic fish you've procured.

He wants you to use your spoils to make fish tacos. Once you bring him fish tacos, he will tell you a story as a reward.
Prepare some fish tacos and speak to the Fisher to proceed!

The Fisher told you a story about a lovely mermaid. He wonders if similar stories exist in Cinder's Cradle, which are relatively barren and possess no large bodies of water to speak of.

Perhaps you will be able to find something of use when looking around old ruins with creeks or ponds.
