How might one go about entering Labradorra? I don't believe there is any hints in-game currently, except for us having to battle it at some point, but as seen with PULSE Clawitzer the PULSE can be disabled without actually destroying it. I suspect the disabling of the barrier would probably be an inside job. We have just dealt with Bennett and his defection from Team Meteor; someone who has access to the city but I query his courage/motivation to do such a thing. Taka(Zekrom)/Solaris(Reshiram) could also be a possibility, but there is the issue that both of them were seen with Sirius chasing after them in a menacing way, so they would probably struggle to deal with the PULSE and Sirius at the same time, and we don't know if Solaris would fully commit to backstabbing his 'own' team. Fern was supposed to be the hero of the prophecy, but there hasn't been any sign of him standing up to Team Meteor since he joined. If the Calcenon Control Centre connected to Labradorra uninterrupted, I'm sure Saphira would have found it when she went to investigate. The only other possibility I could think of would be Lin. It's been suggested that she wants the player to do all the work collecting the keys, and she is probably aware that all the keys are held by the Elite 4. I suspect that she might order the removal of the barrier so that the player can obtain the 18th gym badge and advance to the league(which from a hand-drawn map of the region, I believe victory road starts in Labradorra?). Team Meteor would likely fall after we reclaim Labradorra, and El might side with us as Solaris' loyalty is being questioned and El is loyal to Solaris, so getting the four keys would probably happen after we beat the elite four. Lin doesn't need Team Meteor if we are doing the work of collecting the keys, so the defeat of Team Meteor wouldn't matter to her, so she could just hide and strike as soon as we get the four keys and then run off to the Citae Arc d'Astrae Aerie.
