Selina walked up to the group and said "But before that, you've got a meeting with some Lucario" She would then direct then to Mustard office where Mei and Cammy were helping an elderly Lucario who was blind in both eyes but he sensed their approach and said "Greeting humans, my sister's Mei and Cammy have filled me in on what it is you seek. Sadly, I can't agree to it, epically with how much darkness three members of your team carry, epically one who darkness matches the one who attacked our village many years ago" 
He pointed to Liam, Shinranui and Selina before adding "but I have also been watching and are well aware that the one called Chuck has gained Kubfu and Master Musterd seems to have faith in you, so Chuck North, you will be the one who will gain our tribe trust, take that Kubfu on a journey, fully complete Master Mustard training and we will allow you and your friends into our village to obtain the Auravellas Flower to cure your special pokemon of their Berserker gene"

Selina felt like she had to ask "Elder, you say that myself, Liam and Shinranui would not be allowed in your village because of the darkness inside our heart, but why does that hurt Chuck and Jen too?". The elder answered her "You are a group, are you not? We are just being careful, the others and myself still remember what transpired when we let a group in, who only had one darkness in their group, my older sisters were taken alongside countless other, and only my sisters Mei and Cammy survived, but many other lives were lost in the battle to prevent from being taken in the first place".

The Elder though about something else before pointing to Liam once more "Tell me, does the human known as Nigal Knightwing still live?" "He does, despite Liam and Co best efforts, Nigal keep slipping away" Mei told him. "Then it is as we expected too, Nigal lead the attack on our tribe over 300 years ago" The Elder told the group getting a gasp from Serina. "After the attack, we dedicated a lot of resources and time into finding everything about him to try and rescue you all. His face has appeared in many old photo and the aura itself believe that he is far older then he appeared. Our research with the help of Master Mustard once he moved and built his dojo here, reviled that Nigal Knightwing has been alive since before the other Regions came about, when only the Hisui and Ransei regions were around, we discovered that Nigal Knightwing true name was Nobunaga Kazuma, the younger brother of Nobunaga Oda, who survived the destruction of the Ransei region before it became the region known today as Hoenn"
