Shadow Seer (Rogue Merchant Book #3): LitRPG Series

Meet Cat. He thinks everything has its price. You can pay in gold, or you pay in steel. And for the right price, even the entire Sphere of Worlds can be bought.

Ever the merchant, he pays in souls, freeing the Goddess of Darkness in the astral fortress of Pandorum and becoming the archnemesis of the most powerful alliance in all of Sphere. Even as an enormous bounty is placed on his head with hunters trailing his every move, he never wavers. His patron, the God of Shadows, sends Cat to the twilight world of the Hole to find the third of the seven Keys. There, the merchant will have to traverse the dangerous waters of an underground ocean to reach the Isle of Madness, proving once again to be worthy of the divine favor.
