Walkthrough

 * This quest is received as an extension to Fruitful Alliance, as part of Ruāsare's terms of alliance with the Huana. It can also be done concurrently to Clearing Out Crookspur.
 * This is a quest that can be tackled in a variety of ways, but ultimately requires both freeing the Wahaki slaves from captivity, and purging the slavers from the island. For a detailed walkthrough, see the quest A Shrewd Proposition.
 * Note that once you free either of the slaves, the fort will be put on alert. If you have started Tip of the Spear, this will fail that quest, you will also be unable to do Captain Furrante's side of A Shrewd Proposition.
 * Once Master Kua is dead, take his head and return to Ruāsare to complete the quest.
