A queen (with no king) tasks you with rescuing her many princesses. She guides you to where they are imprisoned.
It's peculiar that she supposedly has so many.
Other kingdoms are also missing their princesses, but have no idea where they are.
As each princess is returned to Yipe, they are kept safely in the dungeon. Allegedly to prevent them getting abducted again.

The queen is actually "priming" the princesses for marriage alliances to make Yipe the single most powerful kingdom.
?  Alliances with powerful races that the other kingdoms would never consider.
She orchestrated their abductions from their original kingdoms, but used monsters to hide her involvement.

Meanwhile, the Queen's monsters want their toys back.
And most of the princesses have been fully "trained" for sex.

------------------------------------------------
queen is actually queen of the bunnygirls.  (or maybe the original bunnygirl born from a magic bunny + human)
and wants to turn the abducted princesses into more bunnygirls.  (create/expand her race)
They are not born they are created, by a magical race of amorous rabbits.
The seemingly innocuous creatures are her minions, and appear in oddly dangerous places.

bunnies are naturally amorous and pervy by nature.
a group of them acquired magic somehow, and grew ambitious.

the monsters of the world were born from an ancient war fought with magic.
to end the destruction, magic was stolen away from the human race.
over time, the monsters have gradually grown less violent, as memories of war fade over generations.
the future seems hopeful.
but one day a bunch of monsters suddenly abduct some people.  well-protected people.  the monsters never seemed organized before.

later their motives turn out to be amorous.  this is ironically encouraging since it's not violent, but still troublesome.
but why now?

a legend of the magic scepter, long hidden away deep in a remote forest where no greedy people would ever find it.
hidden by the fairies with a magic barrier to keep people out... but only people.
but this plan was not fully thought out.  nobody considered the effect the scepter might have on the forest's animals.
or that animals might dig past the barrier.  it didn't seem to matter.  nobody cared about the mundane actions of common animals.  their free passage is healthy for the forest.  without them there would be no forest to hide anything.
but the forest grew "haunted" by strange effects.
unwatched, the animals grew ancient, intelligent, and peculiar.

meanwhile, a new and oddly benign race of "monsters" called bunnygirls have been appearing in the world.  but only in remote barely-inhabited corners.  But they are not monsters. They are humans transformed by (or maybe hybrids born from?) ancient magically-infused animals.
but they are actually everywhere.  in a hidden underground kingdom, with extremely well-hidden enterances.  the rabbit minions emerge in seemingly impossible locations from "their" burrows.
a couple human scholars regard this phenmonenon as a mere evolutionary curiosity.  getting better at digging through surprising materials.
humans fully transformed into bunnygirls inherited bunny instincts and dug homes underground.  the kingdom formed naturally as they found each other underground.
they manipulate and train the beasts and monsters of the world through sexual enticement and seduction.
they do not need to be powerful or strong.  they only need to be pursuasive.
they tease humans as readily as any other creature.
but now they are preparing to train the human race.

this is not some impending "apocolypse" in the traditional sense
no malevolent intent
but an equally extreme change is looming.
a cryptic prophecy.
it's not clear to the fairy seers whether this needs to be addressed.  it's not a threat, it's a change.
why would there even be a phrophecy if it's not a warning?  but the outcome doesn't sound like anything bad.  maybe just a warning of major change?
a couple of very remote human settlements have already been affected.  Chosen by the bunnygirls as tests of what works.
one is already fully in their thrall, with a completely new culture.  (amazon race)  (some have already started turning into bunnygirls)  (their remembered or recorded history reveals the transition)
another has adopted a symbiotic relationship that is very gradually changing their culture.  they're oblivious of the eventual result.
