Mending

Metaphysical / Paranormal event

For the first time since he blessed the world, The Star Forger came back to his realm after he too felt the ripple in the astral created by Aurora. He quickly noticed that the veil hiding and protecting the realms had weakened, and reinforced it. He then banished the otherworldly gods who had invaded the material plane.
  He took pity upon the races brought within by said gods, and let them stay after making them vow to forget their old masters. While the chromatic dragons were a perversion of his proudest creation, he saw potential in them, and allowed them to remain as well.
  Though he wished to do the same with the fiends who had invaded even before the gods, the fractured abyss was the creation of another overgod, he knew its traces would remain and would only delay another invasion. As such he instead opted to shunt the war Realm into an isolated portion of the Astral Plane, limiting their direct influence over the Material Plane.
