When our galaxy warped into the new space our sensors immediately reported the results we hoped for anxiously. An empty space, devoid of anything but our galaxy.
After a short period of celebration, in which our 2.1 trillion planets joined in ecstatic telepathic mental union, we opened the matter-gates (known to you as black holes). From the steady accretion of radiation pouring through our newly opened floodgates we began forming new star clusters with which to seed this fertile empty space.
The first galaxies generated we set into orbit of our central system. Later galaxies we accelerated to great speeds and flung across the space. We plan to seed this entire space with life, filling it to the brim.
