The logging town of Northsap was founded in Darkmoon Vale in 4452 AR. Northsap was abandoned in 4573 AR with the foundation of Falcon's Hollow.
The town was established at the base of a lava plug tower. Its buildings were built from stone quarried from the lava plug, and most of the roofless ruins of these buildings still stand. Northsap's ruins occasionally house dangerous creatures, like kobolds or hungry ghouls. The Diamond Regiment occasionally sends mercenaries or adventurers to check the ruins.
