What is the importance of Parham Plantation in the novel, Oroonoko?

When Oroonoko eventually arrives in Surinam, after being kidnapped and enslaved, he is taken to Parham Plantation, where the owner, Mr. Trefry, recognizes his status and affords him the treatment (i.e. as a guest) he feels Oroonoko deserves. By contrast, Parham Plantation (the home of the narrator) is also the setting for Oroonoko's torture and execution, following his leading of the slave rebellion.
