When the Wizarding World was exposed late 21st century, Apparation was, and still is to this day, considered one of the most frustrating things for a non magical to fight against. Neither muggle or Magical would realize that it would one day help against an enemy that united both worlds against them
With the Addition of the Prothean Ruins found on Mars, and with the magical properties that were public to non magical and magical alike, Humanity jumped from several centuries head to nearly a millennia.
It was nine years later that Muggle and Magical alike were united as one when it was made known to all that an unknown alien species had attacked a Human ship studying one of the dormant relays, and mater that Shanxi was being invaded by said hostile race.
The 'Big Birds' as dubbed by British Auror Miles Nott when he first spotted them, were overwhelmed by the sudden assault by Magical Forces out of nowhere that arrived with the non magical ones.
Turians, as Humanity would come to know the species to be called shortly after, were completely overwhelmed by the Magical forces that would appear randomly across the battlefield then vanish, firing spells at them that bypassed shield completely, or got wounded non magicals away. Nor did command believe the reports of the humans flying through the air on tree limbs.
More unprepared for the Giants, Dragons and Centaurs that had come to aid the soldiers.
Shanxi was turned from complete Turian occupation to liberated in just a few hours.
The Space Battle went just as poorly once the Magical forces discovered that they could apparate onto Turian ships as easily as a Human, taking out surprised bridges in seconds, or mind controlling entire crews to fire on their own ships or slaughter each other.
By the time the Citadel had discovered the war between Humanity and Turians, Humans had already devastated dozens of Turian ships or captured them alongside several Turian colonies, that were used to hold Turian Prisoners
Upon Asari peace talks between the two races, the Citadel races were stunned to learn that it was not an alliance of different species from different planets, but a group from one single planet, and the flashing lights were not advanced technology as assumed, but actual magic.
Due to their competence in being able to take on the Turian Military head on, and the many magical abilities that to this day have only appeared in Humans, Humanity quickly became a Council Member Species, threatening the Turian Military superiority they'd be known for over 1000 years.
