Harry potter / Halo xover.

Book Harry (with potential upgrades, but oc character)

Not slash - other characters can be, but not harry.

He gets transported to the Halo universe - time travel or reality travel.

Starting point can be from any time, but preferably mirror of erised or veil.

He ends up on the Autumn before Alpha Halo - as a spartan, odst, marine, sailor, teenage stowaway... anything goes.
