Further Research is the last quest given by the Sea Scholar in the sea scholar's quest line.
Walkthrough EditAfter you delivered the book "Life, Death and the Sea" and finished Philosophical Pursuit, you can talk to the sea scholar:
The Sea Scholar's Token can be acquired by selling almost any book to a Sea Scholar. You can trade multiple copies of a book. For example, the book "Guide to Buried Treasure" can be bought from a merchant and then turned in to the sea scholar.
For each 7 tokens delivered, you will be rewarded with a unique item. This process is random and can be repeated infinitely, so it's possible to have multiple duplicate items.
