"But of course, we already said we would take care of our clients"

As nice as that sounded, the truth was that their were really the ones in charge of going to the hidden land and temporal tower, and if what Alice said was right, they would need someone pure of heart to arrive there, and while none of the members of the Bad Rulers were really evil, it would be laughable to suppose that any of them were completely "pure of heart", that's what the ninjask and his brother would provide, if they were heroes as they said. 

"So it's everyone ready? let's go into the brine cave"

The first floors were easy, even though they were often attacked, the wild pokemon came in low numbers, one or two at the time, usually a kingler, a gastrodon or a walrein. The Ghost group compensated their relative low level (compared to the SneakyNinja team) by teamwork (if you can call teamwork ganging up altogether at the same time on the same enemy), a tactic rather brute, but effective. While Déspota saw on a couple of times how Jacks and Vince were attacking as well, true is that he never saw Alice attacking even once, but she was at the back and the banette was leading the way, so it could be that he was simply not seeing much. 

After some time walking/floating (it's ironical how the banette was the only one who needed to touch the floor) they finally reached the final 15th underground floor, and they could just feel that the end was near, what would be the transport pokemon that would carry them to the hidden land?
Just when they stepped into a spacious room, suddenly a bunch of wild pokemon fell from the ceiling, two omastar, a kabutops, a pair of dragonairs, three staryu a tentacool and a walrein, Autócrata pushed Déspota quickly to one side just when a water gun was about to hit him

"it's a monster house, watch out!"

The whole party was cornered, they have been able to advance thanks to the enemies being just one or two at the time, but now that they were facing a lot of them they would need to fight for real.
