I'm pretty sure that Salem has been waging a campaign to whittle away and humankind's champions for some time. I am certain that she was responsible for Summer's death (likely in an attempt to eliminate the Silver-Eyed Warrior from the equation). She may even be responsible for the destruction of the majority of Atlas, thus severely weakening the population base and cultural strength of Remnant's strongest military power.

With this in mind, the other Maidens are almost certainly heavily guarded and out-of-play as letting them out in the field would invite an attack from one of Salem's pawns.
