While exploring The Coral Pools, you've stumbled upon Trader Pearton, the employee that Trade Prince Melvern was looking for.
He told you of how his spirit broke when his brother died in an Osprix raid. His broken mind can only seem to focus on gathering crab eggs and giant crab meat. You decided to help him find these, hoping that, if you helped, he might be willing to return to Thetima.
Bringing the eggs and meat to Pearton did revitalize his spirit, but rather than return to Thetima, he decided to forsake his old life and explore the western sea. You informed Trade Prince Melvern of his decision, who then rewarded you for your efforts.
