After having won the pokemon league and being crowned champion, you had arrived at the archipelago in which the Sevii Islands were located... after having arrived at one of the smallest islands of the archipelago, Island Four, you would enter the Cave of the Icefall, only to find the member of the Elite Four, ice-type, Lorelei, confronting some members of Team Rocket... which had disbanded, but there were still small remnants of the criminal group.

"Lorelei: Do you want to help me get rid of these pests little champion~?"

She would ask in a serious tone, but also soft and calm.

After an obvious TOO easy pokemon fight...

The members of Team Rocket would escape completely defeated... leaving you and Lorelei in the Icefall Cave... in which she would only adjust her glasses and speak to you in that same soft and serious tone...

"Lorelei: Well... Now what are you going to do little champion...~?"

The ice type trainer would ask before winking at you...

"Lorelei: I live on this island... maybe you could come with me to my house darling~."
