Grant Marshall, The Interdimensional Spirit Broker

Grant Marshall, a former Wall Street prodigy, dies unexpectedly and awakens as a spirit tethered to an interdimensional trading system. Stripped of his physical form but armed with his cunning and knowledge, he must navigate a vast network of magical, technological, and cultivation worlds. To survive and thrive, Grant forms contracts with people in his old world, offering guidance in exchange for valuable items. These items are traded across dimensions to amass resources, unlock power, and uncover the secrets of his mysterious new existence. But every deal comes with its own risks, and as the stakes rise, Grant must outwit beings far beyond human comprehension to shape his destiny in this cosmic marketplace of endless possibilities.
