The Serpent River:

South Reach

Map of the Lower Serpent River
Ayodhya
Start of the Pilgrimage Route which ends at the Cliff City of Syrtis; also the location of an Obsidiman Liferock.  The Green Arrow Path met with High Magus Theodorus there.
 
Erengazor
A small kaer and town along the lower Serpent River, halfway between the Towers of House K'tenshin and Lake Pyros in the Servos Jungle.  Inhabited primarily by T'skrangs and Humans; home to the Citadel, where the Green Arrow Path Company is headquartered.
 
Fallam
Large city at the confluence of the Lower Serpent River and the Iontos River, just downstream of House K'tenshin's headquarters.
 
Lake Pyros
Ringed by many abandoned villages and often raided by House Hengyoke.  This is where the youngest members of the Green Arrow Path saw a dragon and Theran vedettes fight.
 
Lorin
A village of Cathan Humans and T'skrangs along the Serpent River, a day's travel by boat downstream of Erengazor (or about two days' travel coming back against the current.  The youngest members of the Green Arrow Path recently put a stop to some thievery there.
 
Niall Meru Plantation
This plantation operated by niall Meru of House K'tenshin and situated one day upstream of Erengazor by riverboat is less than a year old, and therefore still unnamed.  It is operated through slave labour.  The Foolish Venture showboat stopped there when the young Green Arrow Path recruits were sent out to Syrtis.
 
Sixteen Towers
The great city of House K'tenshin at the confluence of the Servos, Serpent, and Byrose Rivers.
 
Wester's Crossing
Small village east of Trosk, that acts as a staging point for adventurers intent on exploring the Badlands.
