The three Sins searched every area of hell using the mirrors in the throne room. Each one was directly connected to a different realm, a different level… there was no place in this universe that the Gatekeeper could have slithered off to and not have it shown on the mirrors.

"You don't start an uprising in Hell and just vanish when victory is in your sight," growled Envy as he took another second of mirrors and started searching them. "He had our backs against the wall, and as soon as he got the killing shot, he simply vanishes? No. He has to be hiding somewhere."
"I don't know," muttered Lust hesitantly as he looked through the section of mirrors in front of him. "He had us bent over with our pants down. There is no way that the demon who had planned this hostile takeover went into hiding."
