A quick briefing later in the HQ (treehouse)...
"So, Mira got a 'Random Creation'-disease, and now she wants to destroy a Dungeon so she is allowed to use it more?" - Noire
"Spot on." - Garami
"NO, IT'S NOT! Not that bad, at least. B-but if you also get to know the sweet temptation of scoring something big-" - Mira
"Yup, definitely a disease." - Alf
"Disease." - Iron & Revi
"No, it's NOOOT!! And Garami, you were also all for attacking the place!" - Mira
Yeah, yeah..., doesn't change the fact that she's got a gambling problem.
"Ehem, then, back to business. The reason I wanna take down this Dungeon is divided into three. First, the Dungeon is just an hour's walk away from ours. Since there's no telling if they are gonna attack us if they get to know about our existence, I prefer to strike now as we have the advantage." - Garami
"They didn't notice you guys?" - Alf
"We were spying from the top of a large dune, so it should be alright." - Mira
