so this the same zeta halo that mendicant bias stole and the same one used against rebelling san 'shyuum quarantine worlds. the very same one isodidact shrunk from it's original 30,000 km to it's current standard size of 10,000 km the very same zeta and i quote from Primordium "At the command of the Didact, who rarely commanded his wife about anything, those processed by the Composer, those who remained on the fog-shrouded wheel, along with the remains of all the other Flood victims and the deactivated Graveminds - of which ten had already formed - and the last of the functioning monitors keeping perpetual watch - all of the wheel and the wheel itself were sent through a portal for one last time, never to be used in that same way again. It was known as Installation 07. It has become a sacred tomb for millions, though some may still live.
