It's gleeeeeeeeeeeaming crystal ice! So pretty! So deadly! There's so much ice enchanted around it you can't even see who's inside. The scent is undeniable though - that's definitely a Lucy inside that coffin. No more thumping or voices from there though, it's just quiet. It also seems to be the kind of enchanted ice to be resistant to magic in general - whoever made it did not want the ice to be melted easily, if at all. Physically breaking it though - pff, surely no one's strong enough to do THAT. That's almost a foot of ice!
