After the Hogwarts battle and she graduated. Hermione spent her time to explored and learned about the veil who took Harry godfather Sirius Black.
Actually, at first it's just something she does for fill her free times when she met a deadlocked about her research to restore her parents memory, but then when she stumbled a particular book on the Black library which conspired about theories that people who fall into the veil is not death but transport to another dimension...she became obsessed with it.
After 4 months of researching and studying an old ritual, she finally found a way to bring Sirius Black to a living world...er...back to their world. Actually, she wanted to tell Harry when she discovered it but after some thought and a possible chance that maybe she fail she didn't.
So after a week of preparation, She sneaks into the department of mystery that surprisingly doesn't have a high security and start her experiment.
Everything run normally and in accordance with her estimates...but when she think she is succeeded and her mouth speaks the last word of her spell...the veil is rocking violently and she felt everything around her vibrates...before with a loud bang the roof above her head collapse and Hermione knew no more.
Hermione wakes up with worst headache she ever had and a very aching body. She actually thinks that she died when her experiment failed and the roof fell on her head.
She even can imagine Ron and Harry voice when they knew about her foolishness.
"You are a witch Hermione...use your wand and produce a shield to protect you...!"
"yeah...what a witch" She groaned.
Hermione knew something is definitely wrong when she looked at herself and realized that somehow she was in a desert with the sun beating down on her. No rumble of ruins rooftop or wall around her and no people or auror running around because of exploding sound...and she has a sinking feeling that she is not in England anymore.
"okay, keep breathing and try to think."
Keeping her eyes closed and her limbs loose, she assessed herself and as much as she could determine of her surroundings.
Beside her headache, she didn't have any mortal injured. She still has her wand and beside herself, nobody is around her and she can see that for 100 meters ahead..no building around her too.
She sat herself up and then she knew that something is totally wrong with her body...with a sinking feeling she realized that her body was much smaller than it should be. And not as if she'd been shrunk, but as if she'd been de-aged. Her proportions were those of a toddler - flat chested and pudgy with lingering baby fat.
She cursed and then cursed again when her voice came out in a little girl's high pitched instead of her mature one.
"Bother. These sorts of things are supposed to happen to Harry, not me" she groused.
okay, first her spell is a total failure and because of that and unknown force instead of died she transported to different dimension beside her world and became toddler again. With twelve or maybe fourteen years of her life be such kind of payment fee for herself to be able to transport to this world.
Second...she was alone in a desert without people, building, tree, lake or something for miles ahead of her.
And the last her magic...her last hope for escape from this nightmare is totally useless...her magical core is so tiny and unstable like something that you could find in children and make her utterly totally useless eighteen years old in trapped inside four years old body.
Before she realized it Hermione cried...she wailed and scream her voice out.
She cursed herself for her curious nature and for the god or any kind of forced that land her in this ridiculous situation.
For twenty minutes beside her cried and wailed nothing can't be heard in the desert. But when her tears are reduced to hiccups, Hermione can feel that something larger is coming closer to her.
Hermione stood up, wincing her eyes to see despite the dust of sand to the things that come to her.
Carriage...a carriage or a cage full of woman and children appears in front of her. From the disgruntled look, rags of clothes and chains around their neck and hand, she knew that they are not just ordinary citizen...this carriage in front of her is full of slaves...human slaves.
Hermione swallows the bile that stuck in her throat...when one of the horse riders finally know about her existence and held up his hand to stop his entourage.
"hoho...look at this." The man said with a grin in his face.
"where are your parent-child?" he asked after he dismounted himself from his horse.
Her body automatically flinch and Hermione took a step backward from the man that she knew was a slave trader.
"don't afraid child...I will not hurt you if you obey me." The man said again and hold up his hand toward her.
"don't touch me" Hermione snarled and took another step backward. Her brain is frantically thinking of a way to escape herself from becoming a slave.
Hermione knew she can't run and escape the man before he hauled up her ass in the air and throw herself into the cage.
She also can't use her wand to disarmed the man or simply make herself invisible and then escape.
Her feeble magical core doesn't allow herself to use magic, but maybe...maybe she can produce accidental magic and then disappeared from here.
"insolent little bitch," the man said and raised his hand to hit her but before he could a voice make his stop.
"don't bruise the merchandise, Bernard."
Before the man can say anything or do anything else, Hermione makes a quick dash and run. Her body still aching and her little leg stumbles many times but Hermione keep running, she knew without a doubt that the man or another slave trader chasing after her.
"make me disappear from here...bring me to another place." She said under her breath.
Hermione closed her eyes and tried to focus herself with every fiber of her body.
"I want to go to another place...bring me to another place!" She keeps repeating inside her mind.
Sirius...bring me to Sirius...
"BRING ME TO SIRIUS BLACK!" Hermione screamed and then with wrenching feeling in her gut Hermione knew that finally something good happening to her.
When nausea in her stomach disappear and she didn't have a thought to throw up her last meal. Hermione opens her eyes.
A pair of gray eyes that she recognized stared back at her. Sirius looks younger and more healthy than she remembered. He was dressed like an actor from medieval era completed with shining and gleaming dark hair.
His eyes were fixed on her and he looked surprised with her appearance.
In that instant, relief wash upon Hermione and she almost wanted to cry again.
"Sirius!" Hermione whispered before finally her fatigue and the energy she used for her attempted to make her appear in front of Sirius weigh her down and Hermione lost her conscious for the second time that day.
