Ah, yes, it sort of did, but they were seemingly formed around it. When you look at the Volume 3 opening it does sort of seem like they are emerging from it in that case. The orb bears every resemblance to the portal Raven goes through so it is reasonable to suggest it is indeed a portal. Perhaps the portal was not really attacking, but rather someone attacked them from the other side of the portal.
