Rowan Kuranes awoke in a new world inside the body of a dying prince. His new body contains terrifying secrets that he has to protect, for inside him lies the key to Eternity. He alone possesses the bloodline of The Ouroboros Serpents with authority over Time. He had Dominion over Sheol, and every soul would be his to keep. He lords over the Host of the Highest Heavens to the Abyssal Horde of the Deepest Hells. Rowan must learn to harness his new abilities and fight against his enemies who would stop at nothing to deprive him of his powers. Yet he must strive to keep a portion of his humanity alive, as he continuously evolves beyond godhood. A/N: There are horror elements, including Eldritch Horror from Lovecraft. A fan of blood-borne and abominable horrors that go bump in the night would love it. Epic action set pieces, and galaxy-wide battles, with an extremely overpowered MC who is a one-man army. https://discord.gg/UVvSCCMnCU Check out my discord.

When Rowan had swept this weapon away from the Undying and sent it hurtling into the horizon, it was already traveling at many times the speed of light, and if Berrion had reacted immediately and say, froze Space/Time, maybe using his higher dimensional powers to bring back the memory of the weapon, he might have been able to stop it, but Berrion was still restricted by the power of the Primordial Weapon.
The same reason Rowan's Time Stack ability could not work on his Bloodline of Sheol to multiply his Soul cultivation, a Primordial weapon could not be manipulated by higher dimensional forces. It was simply too dense.
You could not freeze it in space/time or pluck it from a Memory, it could only be carried by those with great strength and mental fortitude. This was what made Astrolabe so valuable to Rowan at that moment, it only controlled pure speed and with the upgrades it had gotten, it could carry the Primordial Weapon.
