Dalnor/BlackRiver

From Hebridonia Wiki

A large river between Dalnor and Dracnos. It was extensively poisoned by the tieflings until it ran black and poisoned everything down stream of it (see the Dead Lands). It is sited as one of the reasons why the Empire of Dracnos collapsed.

Day of Poison
Poison killed everything. City downstream was depopulated.

Present Day Still black, with a tang, but drinkable.
