Can voidborns go into the "true" void?

in the void, before, there were only the watchers. After, they created the voidborns, but it is not known if they created them in the void kingdom or if they created them in runeterra, as seen in the eye into the abyss: "A creeping shape, ridged and segmented like an insect, began to spread across Olar’s flesh. It hardened, like cooling volcanic rock. A sickening purple light began to pulse within him, like a second heartbeat, radiating out through his flesh." or where icathia once stood: "The seething mass of matter that had consumed them lay like a shroud over the flesh it had consumed. Its surface was undulant, and swelling blisters of glistening matter burst open with frothing birth-sacs that twisted and unfolded like newborn animals." in the universe, we are told that voidborns lives there when they are not sent to runeterra, but in vel'koz bio, we are told that no creatures besides the watchers can enter the "true" void.
