Somnia is evolving, and Murmur is confronted with enemies both old and new. She must lead her guild, Fable, through a dungeon filled with riddles and puzzles to claim the first of twelve keys required to achieve victory. But things are not as they seem: glitches abound, enemies rally against Fable, and unexpected threats move in the shadows.

As the system becomes increasingly complex, Laria and Shayla battle through mismatched coding, and Storm Corp discovers they've left some anomalies in the game out of their reports. Anomalies like Wren. With the report deadline looming, and errors riddling the system, Laria's house of cards is about to come crashing down.
