The New World
The Emerald River
A tributary of the great Hippolyta River in Mazteclopan, the southern continent in The New World. Fairly underexplored due to the presence of hostile natives and dangerous local fauna, it still boasts a small population of hunters, missionaries, traders, and slave runners.
There is a small trading post at the mouth of the river called Point Verdaine.
It may correspond either to the Vaupes/Rio Negro or Caqueta/Japura tributaries or to the Maranon source waters
