The reason why Caliste was so interested in this quest in particular was because of where it was located.
It was in the Elven Kingdom, and it was said that the Elven King had asked for help, which meant that there was a very high chance that he would be able to meet Luther and Fleur's parents again.
It also meant that his revenge would be able to begin.
He would make sure to have some fun with Fleur's mother and Luther's daughter. He would make sure to make them his and let them know.
'I can't wait to see the look in his eyes when I touch his daughter right before his eyes.'
However, that was only the beginning. His real goal was not his daughter, but Luther's wife.
Caliste had no idea who she was yet; however, she was the end goal. She was the one who would hurt Luther the most, which was why Caliste wanted to have her at all costs. But she would also be the hardest to conquer.
Still, just thinking of it gave Caliste a big grin on his face.
