The river began somewhere in the Troll Mountains. It poured over Eldath's Mount at the Green Goddess Falls and into Duskwood Dell. From there, it flowed into the Snakewood. Somewhere below the Green Goddess Falls was an underwater portal that connected to the Wyvernstones of Hullack in northeastern Cormyr. Travelers had to be good-aligned, bearing a holy symbol of Eldath, and in the form of a fish to activate the portal.
When it emerged from the Snakewood, it flowed southwest to Eshpurta. There it merged with Trifin Creek and together they joined the Amstel River.[note 1] Serpent's Tail was a local name for this river because it flowed out of the south end of Snakewood.
During the Shoon Empire, this river flowed through the elvish land of Arundath, the Quiet Forest (as Snakewood was then known). Shoon VII was collecting unicorn horns and slaughtered all the elves who tried to protect them. It was said that the River Rimril flowed red with their blood. For years, fishermen could still find some jewelry and trinkets on their hooks.
- ↑ The map of Eshpurta on page 39 of Lands of Intrigue Book Two: Amn marks the Amstel River as beginning at the convergence of Trifin Creek and the River Rimril, and page 45 describes the river as flowing "from Eshpurta" and being fed by the Khalleshyr and the River Valashar. However, three sources, Empires of the Sands (p. 18), Castle Spulzeer (p. 21), and Lands of Intrigue Book Two: Amn itself (p. 43) indicate that the Amstel River began east of Trollford, the only safe place where it could be crossed for 75 miles. Finally, the wording on page 38 of Lands of Intrigue Book Two: Amn implies that the river began "at Trollford," where the Khalleshyr joined it. It is consistent that Trifin Creek, the Rimril, the Khalleshyr, and the Valashar all fed the Amstel. It seems possible that the north–south fork from Eshpurta and the east–west fork from Trollford were both called the Amstel. It is also possible that the map on page 39 of Lands of Intrigue Book Two: Amn is in error and that references to "from Eshpurta" and "at Trollford" are not meant to be precise but rather as general descriptions of the area, i.e., "near Eshpurta" and "in the region of Trollford." If this latter interpretation is correct, then page 43 of Lands of Intrigue Book Two: Amn would clearly indicate that the River Valashar became the Amstel River when the Khalleshyr joined it 40 miles east of Trollford. According to page 38, then, Trifin Creek flowed into the Rimril at Eshpurta, and it was the Rimril, not the Amstel, that flowed south from Eshpurta. The Rimril then joins the Amstel west of Trollford.
