need help saving slaves

this game.... so adventurers were hired to free illegal slaves taken by war and sold to a city of pirates and lawlessness. they got there, and well im going to sum up a super hilarious long game. they made a deal with a pirate king to kill 2 rebels in exchange for freeing the pirates, they then made a deal with one of the rebels to kill the pirate king and the other rebel, they then made a deal with the other rebel to kill rebel 1. long story short. 2 deal rebels, 1 happy-ish king. 100 free people now
