I don't understand why it would make more sense to send Ganshuk instead of the self proclaimed expert in magic items and their recovery. Explain.
Esme says, "You should both go, but keep a low profile. No reckless wand waving, flashy lights, or sparks emitting from your cane. You should be incognito to scout out the area. Disguise spells, simple clothing, or whatever you can muster to stay out of sight. Forza can go too if need be. Natsu can check for magic items and wards while Ganshuk destroys any evidence that may tie you back to the grave site or the safe house. Take the bag of holding, prepare a 'deep throat' spell, and make sure Ganshuk has acids with him in case he needs to use them to break up materials or body parts. If anything seems out of place, retreat to separate locations, not the house."
