A Voidgate

The Voidgate was on the other side of the mountain, so Alex and Rosemist had to fly over the peaks to get to the other side. There, hidden in the fog, deep within a cave guarded by another Divine beast —a Six-Tailed Sword Snake— was the glowing purple and silver Voidgate.

Rosemist stood next to Alex as he peered into the thin sliver in the fabric of reality, through which he could see into another dimension that ran alongside their current world.

"I've been hoping to find one for a long time now," Alex said, his awed expression unchanging.

"You wanted to find one? Why?" Rosemist asked.

"I've been trying to learn more Dao of Time and Space, and as far as I know, Voidgates are the best places to learn it," he said.

"Hmm." Rosemist didn't immediately answer. "It is indeed a good place to train, but I don't know how useful this can be for you. The crack isn't too wide, and not much of the aura leaves the inside."
