It was the same space that Atlas found himself in last time, but when the ground fell away, it was not a puzzle-like array of floating tiles.
Rather, a formation activated and the entire floor changed. The ground under Atlas' feet became sand and rose into a hill while all around, an environment was created.
There was a jungle off the beach that led deep into the island, while the entire shore was surrounded by an ocean that looked to extend into the beyond.
It was all simulated. This was not a real world that extended into infinity, but it truly made one feel like it was.
But, the Challenger in question would only have a few moments to feel such things before they suddenly found themselves in a precarious situation.
BOOM!
Atlas abruptly jumped back and started running without looking back. In that same moment, a huge entity burst out of the sand dune, its gaping maw aiming to consume him in a single bite.
'A Sovereign Sand Worm.'
