Ves retained so many design spirits these days that the addition of another one started to become routine.
Compared to the Titania who was still being indoctrinated by his other design spirits, the emergence of Kalo was not that notable.
Kalo was a completely new spiritual product that did not have an inkling of the history and memories of the Titania. It started off with nothing but the materials derived from its ingredients along with whatever knowledge Ves had imprinted on his new creation.
Right now, Kalo was extremely weak and fragile. It did not benefit from accelerated growth because Ves chose to save his limited reserves of universal life energy.
He was willing to accelerate the growth of important entities such as Vulcan, but Kalo simply wasn't as important.
