The maple tree stands sentinel in the Canadian wilderness, a silent witness to the unfolding of time. In 1912, a disgraced aristocrat stumbles upon it and experiences something impossible. In 2020, a young woman films it before her mysterious disappearance. In 2203, a novelist writes about it in a pandemic narrative that becomes eerily prophetic. In 2401, a time traveler investigates these incidents, discovering they're all connected by inexplicable moments when reality itself seems to fracture. These temporal anomalies form the heart of "Sea of Tranquility," a mesmerizing exploration of time, simulation theory, and what it means to be human in a universe where reality itself may be an illusion.
