There were three figures located in the dark void outside this hidden dimension. They were the black-robed Ji Ning, the bald, red-robed avatar of Autarch Titanos, and the skinny, black-robed avatar of Autarch Mogg.

"A spatial ripple!" Autarch Titanos revealed a look of delight, as did the black-robed Ning. Both of them turned to look at Autarch Mogg.
The black-robed Ning said, "Bowenya probably fled out of the hidden dimension."
