The Trillia Massacre was an event involving dangerous creatures known as rathtars. During this incident, a number of beings were killed and eaten by rathtars. Finn was familiar with the event, and hoped that Rey hadn't heard of it due to its extremely vile and depraved reputation, with his ultimately confirming that she hadn't heard of it when dealing with an escaped rathtar aboard the Eravana.
