So eventually these two will meet in the Exiled Light. You'll get a bit more, but as you can see, Harley isn't a fan. Coraline on the other hand is her biggest fan, a city girl from an underwater city hearing stories of the MoonRiser apprentice taking on the most dangerous Monsters. She sees Harley as role model to everyone that they have some ancient potential if they just try to reach it. Maybe she can find her potential in the guild? Meanwhile Harley isn't a fan of her cutesy smile and attitude. She just looks too squishy and- a little floozy. She probably doesn't trust her around her Agni.
