I'll skip some of the explanations, mostly commonly known stuff. Here's were Aro come's in and his connection to Atalanta. The Higher beings in the enemy ranks started pulling creatures from across the multiverse, so Aro merely did the same allowing them to summon effectively, as Mashu's shield was needed. He'll also make all servants be able to walk in Chaldea, as if it is an extension of the Hall of Heroes. So there, he won't fight but will guarantee an even playing field.

BTW, what do you think about the enemy, the beast? The Brumak?
