Dragged from their disastrous westward hunt for a phantom peak in the Jagged Tooth mountains, scholar Ethan Kane and Captain Rourke's battered expedition are violently rerouted by their ruthless, obsessive patron, Julien Devereaux. New, cryptic orders, born from Devereaux's own fevered reinterpretations of Solakari lore, send them eastward into the ancient mountains and misty valleys of the Cherokee Nation in Tennessee. Their new objective: the "Solakari Heartstone," an artifact Devereaux believes is the next key to an unimaginable treasure, supposedly hidden near the sacred town of Chota or along the Tellico River. As they venture into these ancestral lands around 1820-1821, a period fraught with tension as the shadow of Indian Removal looms, they find a nation grappling with encroachment and fear. Their arrival coincides with fresh tragedy: a sacred mound site, deeply revered by the Cherokee, has been brutally desecrated, and a respected elder and wisdom keeper, Yonaguska, has vanished from the site after confronting the defilers. Suspicion immediately falls upon a shadowy U.S. military officer, Major Elias Thorne, who has been seen in the territory, aggressively seeking information about old trails, mineral rights, and Native sacred places. Ethan and his companions are soon confronted by the fierce and intelligent Anawa, Yonaguska's kin. Distrustful of all outsiders but desperate to find her grand-uncle and uncover the truth behind the sacrilege, Anawa issues a challenge: if they are truly scholars and not mere plunderers like Thorne, they will aid her. A tense, uneasy alliance is formed, leading Ethan, Rourke, the still-zealous Moreau, and a handful of their men on a perilous pursuit of Thorne's party, guided by Anawa's intimate knowledge of the mountain wilderness. After a violent confrontation, Yonaguska is rescued, and the immediate threat of Major Thorne is neutralized. With Yonaguska safe, the true nature of the "Heartstone" is revealed. It is not a Solakari gem of worldly power, but a sacred Cherokee river stone, holding the ancestral memories and spiritual guidance of the "First People" - perhaps the very Solakari whom Devereaux seeks. When Anawa sings a song of reverence, the stone glows with an inner light, unveiling a cryptic vision: a westward path, away from the Cherokee highlands, "towards where the sun sleeps on water."Trusting this genuine, if mystical, guidance, the expedition turns west once more. Their journey is an arduous passage through unfamiliar territories, facing near starvation and the constant threat of dwindling supplies. Anawa's profound connection to the land and Yonaguska's ancient counsel become their lifelines, teaching Ethan a deep respect for indigenous wisdom that transcends his book learning. His own scholarly skills are now applied to genuine observation and documentation, as he chronicles their path through lands increasingly scarred by conflict as they enter the Muscogee (Creek) frontier. After surviving desperate trials, including finding water where the earth itself seemed barren, their journey culminates on a bluff overlooking a breathtaking sight: the Mississippi River, the legendary "Father of Waters," where the setting sun indeed appears to rest upon its vast surface, fulfilling the Heartstone's prophecy. A factual report of their journey is dispatched to Devereaux. Though one more clue of the Serpent's Coil Legacy has been deciphered, and a path westward indicated, Julien Devereaux's relentless ambition still casts a long, dark shadow. Now, at the edge of this mighty river, a new chapter of their journey begins. What new challenges, ancient secrets, and human dramas await as they prepare to venture south into the heart of the continent? The quest is far from over, and the true meaning of the legacy remains elusive.
