???: *claps hands*

-Scene Change White realm-

???: Who are you?!?

??? #2: I go by many names God, The World, The Universe, All, One, *points at ???* You but Izuku, You can call me Truth.

Izuku: Where are we? What's that gate?

Truth: That gate is where all the secrets lie. Take a gander.

*Izuku starts to get sucked into the gate*

Truth: See you in a few.

Izuku: *screaming* WAIT!

Izuku falls and sees all the known and unknown information about alchemy. He then appears back in front of truth outside of the gate.

Izuku: Wait! Let me get another look.

Truth: No can do, you need to pay the price now for performing human transmutation.

Izuku: What?

Truth: You can't just think that breaking the law of Equivalent Exchange would have no consequences. A Human is much more complex than just some chemicals, compounds, and elements. I will take your arm from you. Never again will you feel the touch of your mother's grasp on your hand as you walk.

*Izuku looks down and sees his hand start to be ripped and disintegrated by the black hands.*

Izuku: NOOO!

-Scene change-

Amestrice Central Hospital.

???: Major Izuku you're awake!

Izuku: *in a daze* Huh... where am I?

???: Central Hospital sir. You lost your arm performing as Mustang called it. Human Transmutation. What we saw in there was no human...

Izuku: Hughes? Huh. *remembers everything and looks at his missing arm*
Damn it.

Hughes: Yeah it was just up and gone. No, where to be seen just the circle, that creature, and you bleed out.

Izuku: Will I have to retire?

???: No you won't.

Izuku: *shocked* King Bradley Sir! *saluting with his only hand*

Bradley: You may have lost your hand, Major. Being an Alchemist with the ability of ice isn't helping it either but if you go to the Northern wall of Briggs then you could get yourself some Automail better equipped for the cold temperatures for your Alchemy correct?

Izuku: Yes Sir!

Bradley: Then from now until you are fully accustomed to your hand you will be transferred to The Northern Wall of Briggs. Lieutenant Colonel Hughes. Get someone to bring him there just in case someone tries to attack him while he's weak.

Hughes: Yes Sir!

Bradley leaves Izuku and Hughes alone. 

Hughes: Izuku let me go and call some people to escort you. *walks away*

-Timeskip 2 Hours-

Hughes: Izuku, meet two of my subordinates. Second Lieutenant Maria Ross and Corporal Denny Brosh will be escorting you to Briggs.

Maria and Denny: *salutes* Hello sir!

Izuku: Enthusiastic. No need to be so formal around me we are gonna be together for at least a few days.

Maria and Denny: *rubbing the back of their heads* Okay sir.

Izuku: *sigh* This is gonna be a long few days.

-Timeskip 2 Days-

Izuku, Maria, and Denny wearing coats are now just a bit away from the wall when three soldiers approach them.

Briggs solder: Stop who are you?

Izuku: *pulls out his Alchemist Pocket watch*  Major Izuku McDougal.

Briggs solder: We were expecting you to come in.

Maria: This is where we leave Major!

Izuku: Thank you two for everything. *smiling*
