The Eternal Night Empire has been shrouded in fog for three hundred years. The last gold-swallowing sorcerer Athelin woke up from the tyrant's dungeon, losing all her memory, leaving only a string of tattoos on her wrist: "NULL".
She was rescued by the rebels, but was told a shocking truth-she herself was the tyrant who had ruled the empire for ten years, and her amnesia was the price of the "Time Mark" technique she personally cast.
To make matters worse, she can't turn off an innate curse: she can hear the truest voice in everyone's heart. The rebel leader said he trusted her, but in his heart he was thinking about how to use her to find the treasure; his loyal teammates protected her, but in his heart he was afraid that she would start killing again after regaining her memory.
To reclaim her shattered past, she must collect metal weapons scattered across the empire - each one sealing a piece of her memory. But every time she regains a memory, she may discover the cruel crimes she has committed.
When mind reading tells her about everyone's betrayal and fear, and Time Trace allows her to see her own dark history clearly - Aiseline must answer a question:
If you were destined to be a bad person, would you still choose to be a good person?
