Lox was the most suitable candidate to control the Webway tunneling machine.
Even the Emperor was less compatible with it than Lox in this regard.
He had already obtained the authority of the Omnissiah, fused with a leadership module from the multiverse, and wielded the AllSpark, an ancient artifact from Cybertron.
At this moment, Lox had long since surpassed Vashtorr, the Lord of the Forge.
That lesser god of the Warp had never left his home universe to sail into the beyond.
