You will discover Babus and some other enemies. Babus asks if you have information about Marche, whom he says has been destroying the crystals and threatening Mewt's world. Marche tries to hide his identity but Babus realizes that he's Marche, and he and his allies attack you.
The goal is to defeat Babus. The Bishop can cast cure, and also dispel to remove all status ailments. You might want to get rid of him, but to keep the battle short, just go for Babus and use status ailments to reduce the other enemies' abilities to hurt you.
Babus will disappear after saying that he knows what Marche looks like and therefore will have people pursuing him.
